The first step in using primes for finding LCM is to find the factors of the given numbers. The LCM of the given numbers is the product of all the prime factors to their greatest power.
Prime factors of 72 are 23 x 32
Prime factors of 147 are 3 x 72
The LCM of 72 and 147 is 23 x 32 x 72 = 8 x 9 x 49 = 3528

What is the LCM of 147 and 231?
1617Express each number in its prime composition using power notation:147 = 3172231 = 3171111To find LCM, use highest power of each prime across the numbers:LCM = 3172111= 3 x 49 x 11= 1617
What is the LCM of 3 and 17 using prime factorization?
3 and 17 are both prime. Any time you have prime numbers, you multiply them together to get the LCM.
How is the LCM related to the relatively prime numbers?
When two numbers are relatively prime, the LCM will be their product.
How do you find the lcm of three numbers when all of them are prime?
When all of them are prime numbers,then just multiply the numbers to get the LCM of those 3 numbers.
What is the LCM of two co prime numbers?
Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM
