Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 691, 680, 90 i.e. 4228920 smallest integer divisible by all numbers.
Least common multiple (LCM) of 691, 680, 90 is 4228920.
LCM(691, 680, 90) = 4228920
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 691, 680, 90 |
5 | 691, 340, 45 |
691, 68, 9 |
∴ So the LCM of the given numbers is 2 x 5 x 691 x 68 x 9 = 4228920
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 691,680,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,680,90) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(691,680,90) x common factors =1 x 10 = 10
LCM(691,680,90) = ( 691 × 680 × 90 ) / 10
LCM(691,680,90) = 42289200 / 10
LCM(691,680,90) = 4228920
∴ Least Common Multiple of 691,680,90 is 4228920
