LCM for 51 and 102
What's the Least Common Multiple (LCM) of 51 and 102?
Answer
(One hundred two)
Finding LCM for 51 and 102 using GCF of these numbers
The first method to find LCM for numbers 51 and 102 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 51 and 102 is 51, so
LCM = (51 × 102) ÷ 51
LCM = 5,202 ÷ 51
LCM = 102
Finding LCM for 51 and 102 by Listing Multiples
The second method to find LCM for numbers 51 and 102 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 51: 51, 102, 153, 204
Multiples of 102: 102, 204, 306
So the LCM for 51 and 102 is 102
Finding LCM for 51 and 102 by Prime Factorization
Another method to find LCM for numbers 51 and 102 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 51: 3, 17 (exponent form: 31, 171)
All Prime Factors of 102: 2, 3, 17 (exponent form: 21, 31, 171)
31 × 171 × 21 = 102
