LCM for 2 and 53
What's the Least Common Multiple (LCM) of 2 and 53?
Answer
(One hundred six)
Finding LCM for 2 and 53 using GCF of these numbers
The first method to find LCM for numbers 2 and 53 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 2 and 53 is 1, so
LCM = (2 × 53) ÷ 1
LCM = 106 ÷ 1
LCM = 106
Finding LCM for 2 and 53 by Listing Multiples
The second method to find LCM for numbers 2 and 53 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110
Multiples of 53: 53, 106, 159, 212
So the LCM for 2 and 53 is 106
Finding LCM for 2 and 53 by Prime Factorization
Another method to find LCM for numbers 2 and 53 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 2: 2 (exponent form: 21)
All Prime Factors of 53: 53 (exponent form: 531)
21 × 531 = 106
