Answer: LCM of 70 and 75 is 1,050

(One thousand, fifty)

Finding LCM for 70 and 75 using GCF's of these numbers

The first method to find LCM for numbers 70 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 70 and 75 is 5, so

LCM = (70 × 75) ÷ 5

LCM = 5250 ÷ 5

LCM = 1050

Finding LCM for 70 and 75 by Listing Multiples

The second method to find LCM for numbers 70 and 75 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 70: 70, 140, 210, 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190

Multiples of 75: 75, 150, 225, 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200

So the LCM for 70 and 75 is 1050
