Answer: LCM of 25 and 70 is 350

(Three hundred fifty)

Finding LCM for 25 and 70 using GCF's of these numbers

The first method to find LCM for numbers 25 and 70 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 70 is 5, so

LCM = (25 × 70) ÷ 5

LCM = 1750 ÷ 5

LCM = 350

Finding LCM for 25 and 70 by Listing Multiples

The second method to find LCM for numbers 25 and 70 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, 350, 375, 400

Multiples of 70: 70, 140, 210, 280, 350, 420, 490

So the LCM for 25 and 70 is 350

Finding LCM for 25 and 70 by Prime Factorization

Another method to find LCM for numbers 25 and 70 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 25: 5, 5 (exponent form: 52)

All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)

52 × 21 × 71 = 350
