LCM for 38 and 58
What's the Least Common Multiple (LCM) of 38 and 58?
Answer
(One thousand, one hundred two)
Finding LCM for 38 and 58 using GCF of these numbers
The first method to find LCM for numbers 38 and 58 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 38 and 58 is 2, so
LCM = (38 × 58) ÷ 2
LCM = 2204 ÷ 2
LCM = 1102
Finding LCM for 38 and 58 by Listing Multiples
The second method to find LCM for numbers 38 and 58 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 38: 38, 76, 114, 152, 190, 228, 266, 304, 342, 380, 418, 456, 494, 532, 570, 608, 646, 684, 722, 760, 798, 836, 874, 912, 950, 988, 1026, 1064, 1102, 1140, 1178
Multiples of 58: 58, 116, 174, 232, 290, 348, 406, 464, 522, 580, 638, 696, 754, 812, 870, 928, 986, 1044, 1102, 1160, 1218
So the LCM for 38 and 58 is 1102
Finding LCM for 38 and 58 by Prime Factorization
Another method to find LCM for numbers 38 and 58 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 38: 2, 19 (exponent form: 21, 191)
All Prime Factors of 58: 2, 29 (exponent form: 21, 291)
21 × 191 × 291 = 1102
