Answer

LCM of 19 and 38 is 38

(Thirty-eight)

Finding LCM for 19 and 38 using GCF of these numbers

The first method to find LCM for numbers 19 and 38 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 19 and 38 is 19, so

LCM = (19 × 38) ÷ 19

LCM = 722 ÷ 19

LCM = 38

Finding LCM for 19 and 38 by Listing Multiples

The second method to find LCM for numbers 19 and 38 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 19: 19, 38, 57, 76

Multiples of 38: 38, 76, 114

So the LCM for 19 and 38 is 38

Finding LCM for 19 and 38 by Prime Factorization

Another method to find LCM for numbers 19 and 38 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 19: 19 (exponent form: 191)

All Prime Factors of 38: 2, 19 (exponent form: 21, 191)

191 × 21 = 38
