Least Common Multiple of 55,56,20,623

Least Common Multiple (LCM) of 55,56,20,623 is 274120

2	55, 56, 20, 623
2	55, 28, 10, 623
5	55, 14, 5, 623
7	11, 14, 1, 623
	11, 2, 1, 89

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 11 x 2 x 1 x 89 = 274120

Least Common Multiple of 55,56,20,623 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 55,56,20,623 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(55,56,20,623) = 1

common factors(in case of two or more numbers have common factors) = 140

GCF(55,56,20,623) x common factors =1 x 140 = 140

LCM(55,56,20,623) = ( 55 × 56 × 20 × 623 ) / 140

LCM(55,56,20,623) = 38376800 / 140

LCM(55,56,20,623) = 274120

∴ Least Common Multiple of 55,56,20,623 is 274120
