Least Common Multiple of 62,78,62,982 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 62,78,62,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,78,62,982) = 2
common factors(in case of two or more numbers have common factors) = 124
GCF(62,78,62,982) x common factors =2 x 124 = 248
LCM(62,78,62,982) = ( 62 × 78 × 62 × 982 ) / 248
LCM(62,78,62,982) = 294435024 / 248
LCM(62,78,62,982) = 1187238
