LCM for 10 and 43
What's the Least Common Multiple (LCM) of 10 and 43?
Answer
(Four hundred thirty)
Finding LCM for 10 and 43 using GCF of these numbers
The first method to find LCM for numbers 10 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 10 and 43 is 1, so
LCM = (10 × 43) ÷ 1
LCM = 430 ÷ 1
LCM = 430
Finding LCM for 10 and 43 by Listing Multiples
The second method to find LCM for numbers 10 and 43 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
Multiples of 43: 43, 86, 129, 172, 215, 258, 301, 344, 387, 430, 473, 516
So the LCM for 10 and 43 is 430
Finding LCM for 10 and 43 by Prime Factorization
Another method to find LCM for numbers 10 and 43 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 43: 43 (exponent form: 431)
21 × 51 × 431 = 430
