What's the Least Common Multiple (LCM) of 120 and 324?

Answer

LCM of 120 and 324 is
3,240

(Three thousand two hundred forty)

Finding LCM for 120 and 324 using GCF of these numbers

The first method to find LCM for numbers 120 and 324 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 120 and 324 is 12, so

LCM = (120 × 324) ÷ 12

LCM = 38,880 ÷ 12

LCM = 3,240

Finding LCM for 120 and 324 by Listing Multiples

The second method to find LCM for numbers 120 and 324 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 120: 120, 240, 360, 480, 600, 720, 840, 960, 1,080, 1,200, 1,320, 1,440, 1,560, 1,680, 1,800, 1,920, 2,040, 2,160, 2,280, 2,400, 2,520, 2,640, 2,760, 2,880, 3,000, 3,120, 3,240, 3,360, 3,480

Multiples of 324: 324, 648, 972, 1,296, 1,620, 1,944, 2,268, 2,592, 2,916, 3,240, 3,564, 3,888

So the LCM for 120 and 324 is 3,240

Finding LCM for 120 and 324 by Prime Factorization

Another method to find LCM for numbers 120 and 324 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 120: 2, 2, 2, 3, 5 (exponent form: 23, 31, 51)

All Prime Factors of 324: 2, 2, 3, 3, 3, 3 (exponent form: 22, 34)

23 × 34 × 51 = 3,240
