What's the Least Common Multiple (LCM) of 66 and 100?

Answer

LCM of 66 and 100 is
3,300

(Three thousand three hundred)

Finding LCM for 66 and 100 using GCF of these numbers

The first method to find LCM for numbers 66 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 66 and 100 is 2, so

LCM = (66 × 100) ÷ 2

LCM = 6,600 ÷ 2

LCM = 3,300

Finding LCM for 66 and 100 by Listing Multiples

The second method to find LCM for numbers 66 and 100 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 66: 66, 132, 198, 264, 330, 396, 462, 528, 594, 660, 726, 792, 858, 924, 990, 1,056, 1,122, 1,188, 1,254, 1,320, 1,386, 1,452, 1,518, 1,584, 1,650, 1,716, 1,782, 1,848, 1,914, 1,980, 2,046, 2,112, 2,178, 2,244, 2,310, 2,376, 2,442, 2,508, 2,574, 2,640, 2,706, 2,772, 2,838, 2,904, 2,970, 3,036, 3,102, 3,168, 3,234, 3,300, 3,366, 3,432

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000, 1,100, 1,200, 1,300, 1,400, 1,500, 1,600, 1,700, 1,800, 1,900, 2,000, 2,100, 2,200, 2,300, 2,400, 2,500, 2,600, 2,700, 2,800, 2,900, 3,000, 3,100, 3,200, 3,300, 3,400, 3,500
