Least Common Multiple of 27, 70, 42, 770 with GCF Formula

Least Common Multiple of 27,70,42,770

Least Common Multiple (LCM) of 27,70,42,770 is 20790

2	27, 70, 42, 770
3	27, 35, 21, 385
5	9, 35, 7, 385
7	9, 7, 7, 77
	9, 1, 1, 11

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 9 x 1 x 1 x 11 = 20790

Least Common Multiple of 27,70,42,770 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 27,70,42,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(27,70,42,770) = 1

common factors(in case of two or more numbers have common factors) = 2940

GCF(27,70,42,770) x common factors =1 x 2940 = 2940

LCM(27,70,42,770) = ( 27 × 70 × 42 × 770 ) / 2940

LCM(27,70,42,770) = 61122600 / 2940

LCM(27,70,42,770) = 20790

∴ Least Common Multiple of 27,70,42,770 is 20790
