LCM for 10 and 445
What's the Least Common Multiple (LCM) of 10 and 445?
Answer
(Eight hundred ninety)
Finding LCM for 10 and 445 using GCF of these numbers
The first method to find LCM for numbers 10 and 445 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 10 and 445 is 5, so
LCM = (10 × 445) ÷ 5
LCM = 4450 ÷ 5
LCM = 890
Finding LCM for 10 and 445 by Listing Multiples
The second method to find LCM for numbers 10 and 445 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, 510, 520, 530, 540, 550, 560, 570, 580, 590, 600, 610, 620, 630, 640, 650, 660, 670, 680, 690, 700, 710, 720, 730, 740, 750, 760, 770, 780, 790, 800, 810, 820, 830, 840, 850, 860, 870, 880, 890, 900, 910
Multiples of 445: 445, 890, 1335, 1780
So the LCM for 10 and 445 is 890
Finding LCM for 10 and 445 by Prime Factorization
Another method to find LCM for numbers 10 and 445 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 10: 2, 5 (exponent form: 21, 51)
All Prime Factors of 445: 5, 89 (exponent form: 51, 891)
