What is the Least Common Multiple of 98 and 105?
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 98 and 105 is 1470.
LCM(98,105) = 1470
Least Common Multiple of 98 and 105 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 98 and 105, than apply into the LCM equation.
GCF(98,105) = 7
LCM(98,105) = ( 98 × 105) / 7
LCM(98,105) = 10290 / 7
LCM(98,105) = 1470
Least Common Multiple (LCM) of 98 and 105 with Primes
