Answer

LCM of 25 and 28 is 700

(Seven hundred)

Finding LCM for 25 and 28 using GCF of these numbers

The first method to find LCM for numbers 25 and 28 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 28 is 1, so

LCM = (25 × 28) ÷ 1

LCM = 700 ÷ 1

LCM = 700

Finding LCM for 25 and 28 by Listing Multiples

The second method to find LCM for numbers 25 and 28 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 525, 550, 575, 600, 625, 650, 675, 700, 725, 750

Multiples of 28: 28, 56, 84, 112, 140, 168, 196, 224, 252, 280, 308, 336, 364, 392, 420, 448, 476, 504, 532, 560, 588, 616, 644, 672, 700, 728, 756

So the LCM for 25 and 28 is 700

Finding LCM for 25 and 28 by Prime Factorization

Another method to find LCM for numbers 25 and 28 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 28: 2, 2, 7 (exponent form: 22, 71)

52 × 22 × 71 = 700
