Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 45, 61, 77 i.e. 211365 smallest integer divisible by all numbers.
Least common multiple (LCM) of 45, 61, 77 is 211365.
LCM(45, 61, 77) = 211365
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
Given numbers has no common factors except 1. So, there LCM is their product i.e 211365
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 45,61,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,61,77) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(45,61,77) x common factors =1 x 1 = 1
LCM(45,61,77) = ( 45 × 61 × 77 ) / 1
LCM(45,61,77) = 211365 / 1
LCM(45,61,77) = 211365
∴ Least Common Multiple of 45,61,77 is 211365
Here are some samples of LCM of two or more Numbers calculations.
