What's the Least Common Multiple (LCM) of 18 and 49?

Answer

LCM of 18 and 49 is 882

(Eight hundred eighty-two)

Finding LCM for 18 and 49 using GCF of these numbers

The first method to find LCM for numbers 18 and 49 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 49 is 1, so

LCM = (18 × 49) ÷ 1

LCM = 882 ÷ 1

LCM = 882

Finding LCM for 18 and 49 by Listing Multiples

The second method to find LCM for numbers 18 and 49 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324, 342, 360, 378, 396, 414, 432, 450, 468, 486, 504, 522, 540, 558, 576, 594, 612, 630, 648, 666, 684, 702, 720, 738, 756, 774, 792, 810, 828, 846, 864, 882, 900, 918

Multiples of 49: 49, 98, 147, 196, 245, 294, 343, 392, 441, 490, 539, 588, 637, 686, 735, 784, 833, 882, 931, 980

So the LCM for 18 and 49 is 882

Finding LCM for 18 and 49 by Prime Factorization

Another method to find LCM for numbers 18 and 49 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

All Prime Factors of 49: 7, 7 (exponent form: 72)

21 × 32 × 72 = 882
