Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 105, 430, 780, 770, 480 i.e. 20660640 smallest integer divisible by all numbers.
Least common multiple (LCM) of 105, 430, 780, 770, 480 is 20660640.
LCM(105, 430, 780, 770, 480) = 20660640
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 105, 430, 780, 770, 480 |
2 | 105, 215, 390, 385, 240 |
3 | 105, 215, 195, 385, 120 |
5 | 35, 215, 65, 385, 40 |
7 | 7, 43, 13, 77, 8 |
1, 43, 13, 11, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 1 x 43 x 13 x 11 x 8 = 20660640
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 105,430,780,770,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(105,430,780,770,480) = 5
common factors(in case of two or more numbers have common factors) = 126000
GCF(105,430,780,770,480) x common factors =5 x 126000 = 630000
LCM(105,430,780,770,480) = ( 105 × 430 × 780 × 770 × 480 ) / 630000
LCM(105,430,780,770,480) = 13016203200000 / 630000
LCM(105,430,780,770,480) = 20660640
∴ Least Common Multiple of 105,430,780,770,480 is 20660640
