LCM for 90 and 260
What's the Least Common Multiple (LCM) of 90 and 260?
Answer
(Two thousand three hundred forty)
Finding LCM for 90 and 260 using GCF of these numbers
The first method to find LCM for numbers 90 and 260 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 90 and 260 is 10, so
LCM = (90 × 260) ÷ 10
LCM = 23,400 ÷ 10
LCM = 2,340
Finding LCM for 90 and 260 by Listing Multiples
The second method to find LCM for numbers 90 and 260 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 90: 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, 990, 1,080, 1,170, 1,260, 1,350, 1,440, 1,530, 1,620, 1,710, 1,800, 1,890, 1,980, 2,070, 2,160, 2,250, 2,340, 2,430, 2,520
Multiples of 260: 260, 520, 780, 1,040, 1,300, 1,560, 1,820, 2,080, 2,340, 2,600, 2,860
