LCM for 5 and 14
What's the Least Common Multiple (LCM) of 5 and 14?
(Seventy)
Finding LCM for 5 and 14 using GCF's of these numbers
The first method to find LCM for numbers 5 and 14 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 5 and 14 is 1, so
LCM = (5 × 14) ÷ 1
LCM = 70 ÷ 1
LCM = 70
Finding LCM for 5 and 14 by Listing Multiples
The second method to find LCM for numbers 5 and 14 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80
Multiples of 14: 14, 28, 42, 56, 70, 84, 98
So the LCM for 5 and 14 is 70
Finding LCM for 5 and 14 by Prime Factorization
Another method to find LCM for numbers 5 and 14 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 5: 5 (exponent form: 51)
All Prime Factors of 14: 2, 7 (exponent form: 21, 71)
51 × 21 × 71 = 70
