What is the Least Common Multiple of 700 and 707?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
Least common multiple (LCM) of 700 and 707 is 70700.
LCM(700,707) = 70700
Least Common Multiple of 700 and 707 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 700 and 707, than apply into the LCM equation.
GCF(700,707) = 7
LCM(700,707) = ( 700 × 707) / 7
LCM(700,707) = 494900 / 7
LCM(700,707) = 70700
Least Common Multiple (LCM) of 700 and 707 with Primes
