What's the Least Common Multiple (LCM) of 26 and 78?

Answer: LCM of 26 and 78 is 78

(Seventy-eight)

Finding LCM for 26 and 78 using GCF's of these numbers

The first method to find LCM for numbers 26 and 78 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 26 and 78 is 26, so

LCM = (26 × 78) ÷ 26

LCM = 2028 ÷ 26

LCM = 78

Finding LCM for 26 and 78 by Listing Multiples

The second method to find LCM for numbers 26 and 78 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 26: 26, 52, 78, 104, 130

Multiples of 78: 78, 156, 234, 312, 390, [...], 78

So the LCM for 26 and 78 is 78

Finding LCM for 26 and 78 by Prime Factorization

Another method to find LCM for numbers 26 and 78 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 26: 2, 13 (exponent form: 2¹, 13¹)

All Prime Factors of 78: 2, 3, 13 (exponent form: 2¹, 3¹, 13¹)

2¹ × 13¹ × 3¹ = 78
