Least Common Multiple of 2035 and 2043 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2035 and 2043, than apply into the LCM equation.

GCF(2035,2043) = 1
LCM(2035,2043) = ( 2035 × 2043) / 1
LCM(2035,2043) = 4157505 / 1
LCM(2035,2043) = 4157505

Least Common Multiple (LCM) of 2035 and 2043 with Primes
