What's the Least Common Multiple (LCM) of 45 and 46?

Answer

LCM of 45 and 46 is 2,070

(Two thousand, seventy)

Finding LCM for 45 and 46 using GCF of these numbers

The first method to find LCM for numbers 45 and 46 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 45 and 46 is 1, so

LCM = (45 × 46) ÷ 1

LCM = 2070 ÷ 1

LCM = 2070

Finding LCM for 45 and 46 by Listing Multiples

The second method to find LCM for numbers 45 and 46 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360, 405, 450, 495, 540, 585, 630, 675, 720, 765, 810, 855, 900, 945, 990, 1035, 1080, 1125, 1170, 1215, 1260, 1305, 1350, 1395, 1440, 1485, 1530, 1575, 1620, 1665, 1710, 1755, 1800, 1845, 1890, 1935, 1980, 2025, 2070, 2115, 2160

Multiples of 46: 46, 92, 138, 184, 230, 276, 322, 368, 414, 460, 506, 552, 598, 644, 690, 736, 782, 828, 874, 920, 966, 1012, 1058, 1104, 1150, 1196, 1242, 1288, 1334, 1380, 1426, 1472, 1518, 1564, 1610, 1656, 1702, 1748, 1794, 1840, 1886, 1932, 1978, 2024, 2070, 2116, 2162

So the LCM for 45 and 46 is 2070

Finding LCM for 45 and 46 by Prime Factorization

Another method to find LCM for numbers 45 and 46 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 45: 3, 3, 5 (exponent form: 32, 51)

All Prime Factors of 46: 2, 23 (exponent form: 21, 231)

32 × 51 × 21 × 231 = 2070
