LCM for 26 and 52

The first method to find LCM for numbers 26 and 52 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 26 and 52 is 26, so

LCM = (26 × 52) ÷ 26

LCM = 1352 ÷ 26

LCM = 52

The second method to find LCM for numbers 26 and 52 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 26: 26, 52, 78, 104

Multiples of 52: 52, 104, 156, 208, 260, 312, 364, 416, 468, 520, 572, 624, 676, 728, 780, 832, 884, 936, 988, 1040, 1092, 1144, 1196, 1248, 1300, 1352, 1404, 1456, 1508, 1560, 1612, 1664, 1716, 1768,
