Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 77, 22, 561 i.e. 7854 smallest integer divisible by all numbers.
Least common multiple (LCM) of 77, 22, 561 is 7854.
LCM(77, 22, 561) = 7854
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
11 | 77, 22, 561 |
7, 2, 51 |
∴ So the LCM of the given numbers is 11 x 7 x 2 x 51 = 7854
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 77,22,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,22,561) = 11
common factors(in case of two or more numbers have common factors) = 11
GCF(77,22,561) x common factors =11 x 11 = 121
LCM(77,22,561) = ( 77 × 22 × 561 ) / 121
LCM(77,22,561) = 950334 / 121
LCM(77,22,561) = 7854
∴ Least Common Multiple of 77,22,561 is 7854
