LCM for 16 and 19
What's the Least Common Multiple (LCM) of 16 and 19?
(Three hundred four)
Finding LCM for 16 and 19 using GCF's of these numbers
The first method to find LCM for numbers 16 and 19 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 16 and 19 is 1, so
LCM = (16 × 19) ÷ 1
LCM = 304 ÷ 1
LCM = 304
Finding LCM for 16 and 19 by Listing Multiples
The second method to find LCM for numbers 16 and 19 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240, 256, 272, 288, 304, 320, 336
Multiples of 19: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342
So the LCM for 16 and 19 is 304
Finding LCM for 16 and 19 by Prime Factorization
Another method to find LCM for numbers 16 and 19 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 16: 2, 2, 2, 2 (exponent form: 24)
All Prime Factors of 19: 19 (exponent form: 191)
24 × 191 = 304
