What's the Least Common Multiple (LCM) of 22 and 51?

Answer

LCM of 22 and 51 is 1,122

(One thousand, one hundred twenty-two)

Finding LCM for 22 and 51 using GCF of these numbers

The first method to find LCM for numbers 22 and 51 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 22 and 51 is 1, so

LCM = (22 × 51) ÷ 1

LCM = 1122 ÷ 1

LCM = 1122

Finding LCM for 22 and 51 by Listing Multiples

The second method to find LCM for numbers 22 and 51 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, 308, 330, 352, 374, 396, 418, 440, 462, 484, 506, 528, 550, 572, 594, 616, 638, 660, 682, 704, 726, 748, 770, 792, 814, 836, 858, 880, 902, 924, 946, 968, 990, 1012, 1034, 1056, 1078, 1100, 1122, 1144, 1166

Multiples of 51: 51, 102, 153, 204, 255, 306, 357, 408, 459, 510, 561, 612, 663, 714, 765, 816, 867, 918, 969, 1020, 1071, 1122, 1173, 1224

So the LCM for 22 and 51 is 1122

Finding LCM for 22 and 51 by Prime Factorization

Another method to find LCM for numbers 22 and 51 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 22: 2, 11 (exponent form: 21, 111)

All Prime Factors of 51: 3, 17 (exponent form: 31, 171)

21 × 111 × 31 × 171 = 1122
