LCM for 23 and 46

The first method to find LCM for numbers 23 and 46 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 23 and 46 is 23, so

LCM = (23 × 46) ÷ 23

LCM = 1058 ÷ 23

LCM = 46

The second method to find LCM for numbers 23 and 46 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 23: 23, 46, 69, 92

Multiples of 46: 46, 92, 138, 184, 230, 276, 322, 368, 414, 460, 506, 552, 598, 644, 690, 736, 782, 828, 874, 920, 966, 1012, 1058, 1104, 1150, 1196, 1242, 1288, 1334, 1380, 1426, 1472, 1518, 1564,
