LCM for 35 and 70

The first method to find LCM for numbers 35 and 70 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 35 and 70 is 35, so

LCM = (35 × 70) ÷ 35

LCM = 2450 ÷ 35

LCM = 70

The second method to find LCM for numbers 35 and 70 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 35: 35, 70, 105, 140

Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260, 1330, 1400, 1470, 1540, 1610, 1680, 1750, 1820, 1890, 1960, 2030, 2100, 2170, 2240, 2310,
