What's the Least Common Multiple (LCM) of 9 and 80?

Answer: LCM of 9 and 80 is 720

(Seven hundred twenty)

Finding LCM for 9 and 80 using GCF's of these numbers

The first method to find LCM for numbers 9 and 80 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 80 is 1, so

LCM = (9 × 80) ÷ 1

LCM = 720 ÷ 1

LCM = 720

Finding LCM for 9 and 80 by Listing Multiples

The second method to find LCM for numbers 9 and 80 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, 252, 261, 270, 279, 288, 297, 306, 315, 324, 333, 342, 351, 360, 369, 378, 387, 396, 405, 414, 423, 432, 441, 450, 459, 468, 477, 486, 495, 504, 513, 522, 531, 540, 549, 558, 567, 576, 585, 594, 603, 612, 621, 630, 639, 648, 657, 666, 675, 684, 693, 702, 711, 720, 729, 738

Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880

So the LCM for 9 and 80 is 720

Finding LCM for 9 and 80 by Prime Factorization

Another method to find LCM for numbers 9 and 80 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 9: 3, 3 (exponent form: 3²)

All Prime Factors of 80: 2, 2, 2, 2, 5 (exponent form: 2⁴, 5¹)

3² × 2⁴ × 5¹ = 720
