Least Common Multiple of 63,78,60,30 with GCF Formula
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 63,78,60,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,78,60,30) = 3
common factors(in case of two or more numbers have common factors) = 180
GCF(63,78,60,30) x common factors =3 x 180 = 540
LCM(63,78,60,30) = ( 63 × 78 × 60 × 30 ) / 540
LCM(63,78,60,30) = 8845200 / 540
LCM(63,78,60,30) = 16380
