LCM for 7 and 25
What's the Least Common Multiple (LCM) of 7 and 25?
(One hundred seventy-five)
Finding LCM for 7 and 25 using GCF's of these numbers
The first method to find LCM for numbers 7 and 25 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 7 and 25 is 1, so
LCM = (7 × 25) ÷ 1
LCM = 175 ÷ 1
LCM = 175
Finding LCM for 7 and 25 by Listing Multiples
The second method to find LCM for numbers 7 and 25 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, 175, 182, 189
Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225
So the LCM for 7 and 25 is 175
Finding LCM for 7 and 25 by Prime Factorization
Another method to find LCM for numbers 7 and 25 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 7: 7 (exponent form: 71)
All Prime Factors of 25: 5, 5 (exponent form: 52)
71 × 52 = 175
