Least Common Multiple of 24, 28, 42, 423 with GCF Formula

Least Common Multiple of 24,28,42,423

Least Common Multiple (LCM) of 24,28,42,423 is 23688

2	24, 28, 42, 423
2	12, 14, 21, 423
3	6, 7, 21, 423
7	2, 7, 7, 141
	2, 1, 1, 141

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 2 x 1 x 1 x 141 = 23688

Least Common Multiple of 24,28,42,423 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 24,28,42,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(24,28,42,423) = 1

common factors(in case of two or more numbers have common factors) = 504

GCF(24,28,42,423) x common factors =1 x 504 = 504

LCM(24,28,42,423) = ( 24 × 28 × 42 × 423 ) / 504

LCM(24,28,42,423) = 11938752 / 504

LCM(24,28,42,423) = 23688

∴ Least Common Multiple of 24,28,42,423 is 23688
