LCM for 34 and 68

The first method to find LCM for numbers 34 and 68 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 34 and 68 is 34, so

LCM = (34 × 68) ÷ 34

LCM = 2312 ÷ 34

LCM = 68

The second method to find LCM for numbers 34 and 68 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 34: 34, 68, 102, 136

Multiples of 68: 68, 136, 204, 272, 340, 408, 476, 544, 612, 680, 748, 816, 884, 952, 1020, 1088, 1156, 1224, 1292, 1360, 1428, 1496, 1564, 1632, 1700, 1768, 1836, 1904, 1972, 2040, 2108, 2176, 2244,
