How to find LCM by Prime Factorization

- Find all the prime factors of each given number.
- List all the prime numbers found, as many times as they occur most often for any one given number.
- Multiply the list of prime factors together to find the LCM.

The multiples of 60 are 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, etc. These are the first 10 multiples of 60. However, getting the multiples of 60 is quite simple if one knows the multiples of 6.

The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.

To find the HCF, find any prime factors that are in common between the products. Each product contains two 2s and one 3, so use these for the HCF. Cross any numbers used so far off from the products. To find the LCM, multiply the HCF by all the numbers in the products that have not yet been used.

The factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66.

The GCF of 66 and 90 is 6. To calculate the greatest common factor (GCF) of 66 and 90, we need to factor each number (factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66; factors of 90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90) and choose the greatest factor that exactly divides both 66 and 90, i.e., 6.

The LCM of 12 and 20 is 60. To find the least common multiple of 12 and 20, we need to find the multiples of 12 and 20 (multiples of 12 = 12, 24, 36, 48 . . . . 60; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 12 and 20, i.e., 60.

Answer: LCM of 16 and 60 is 240.

The LCM of 64 and 96 is 192. To find the least common multiple (LCM) of 64 and 96, we need to find the multiples of 64 and 96 (multiples of 64 = 64, 128, 192, 256; multiples of 96 = 96, 192, 288, 384) and choose the smallest multiple that is exactly divisible by 64 and 96, i.e., 192.

The LCM of 60 and 72 is 360.

The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. Every even number will have 2 as one of its factors. 60 is a composite number as it has more factors other than 1 and itself.

60 = 1 x 60, 2 x 30, 3 x 20, 4 x 15, 5 x 12, or 6 x 10. Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.

So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 ^{2} × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.

The GCF of 60 and 60 is 60. To calculate the greatest common factor of 60 and 60, we need to find the factors of 60 (factors of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60) and choose the greatest factor that exactly divides both 60 and 60, i.e., 60.

Prime factors are factors of a number that are, themselves, prime numbers. There are many methods to find the prime factors of a number, but one of the most common is to use a prime factor tree.

Therefore, the formula to find LCM of two numbers is, LCM of two numbers = product of two numbers ÷ HCF of two numbers. Note: The LCM of two co-prime numbers is equal to the product of co-prime numbers because the highest common factor of prime numbers is 1.

LCM stands for Least Common Multiple. A multiple is a number you get when you multiply a number by a whole number (greater than 0). A factor is one of the numbers that multiplies by a whole number to get that number. example: the multiples of 8 are 8, 16, 24, 32, 40, 48, 56...
