What's the Least Common Multiple (LCM) of 47 and 55?

Answer

LCM of 47 and 55 is
2,585

(Two thousand five hundred eighty-five)

Finding LCM for 47 and 55 using GCF of these numbers

The first method to find LCM for numbers 47 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 47 and 55 is 1, so

LCM = (47 × 55) ÷ 1

LCM = 2,585 ÷ 1

LCM = 2,585

Finding LCM for 47 and 55 by Listing Multiples

The second method to find LCM for numbers 47 and 55 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 47: 47, 94, 141, 188, 235, 282, 329, 376, 423, 470, 517, 564, 611, 658, 705, 752, 799, 846, 893, 940, 987, 1,034, 1,081, 1,128, 1,175, 1,222, 1,269, 1,316, 1,363, 1,410, 1,457, 1,504, 1,551, 1,598, 1,645, 1,692, 1,739, 1,786, 1,833, 1,880, 1,927, 1,974, 2,021, 2,068, 2,115, 2,162, 2,209, 2,256, 2,303, 2,350, 2,397, 2,444, 2,491, 2,538, 2,585, 2,632, 2,679

Multiples of 55: 55, 110, 165, 220, 275, 330, 385, 440, 495, 550, 605, 660, 715, 770, 825, 880, 935, 990, 1,045, 1,100, 1,155, 1,210, 1,265, 1,320, 1,375, 1,430, 1,485, 1,540, 1,595, 1,650, 1,705, 1,760, 1,815, 1,870, 1,925, 1,980, 2,035, 2,090, 2,145, 2,200, 2,255, 2,310, 2,365, 2,420, 2,475, 2,530, 2,585, 2,640, 2,695
