LCM for 105 and 175
What's the Least Common Multiple (LCM) of 105 and 175?
Answer
(Five hundred twenty-five)
Finding LCM for 105 and 175 using GCF of these numbers
The first method to find LCM for numbers 105 and 175 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 105 and 175 is 35, so
LCM = (105 × 175) ÷ 35
LCM = 18,375 ÷ 35
LCM = 525
Finding LCM for 105 and 175 by Listing Multiples
The second method to find LCM for numbers 105 and 175 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 105: 105, 210, 315, 420, 525, 630, 735
Multiples of 175: 175, 350, 525, 700, 875
So the LCM for 105 and 175 is 525
Finding LCM for 105 and 175 by Prime Factorization
Another method to find LCM for numbers 105 and 175 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)
All Prime Factors of 175: 5, 5, 7 (exponent form: 52, 71)
31 × 52 × 71 = 525
