1,3,9,27,81
Factors of 136
List of positive integer factors of 136 that divides 136 without a remainder.
1,2,4,8,17,34,68,136
Greatest Common Factor
We found the factors 76,81,136 . The biggest common factor number is the GCF number.
So the greatest common factor 76,81,136 is 1.
Lets's calculate LCM of 190,382,561
2 | 190, 382, 561 |
95, 191, 561 |
∴ So the LCM of the given numbers is 2 x 95 x 191 x 561 = 20358690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20358690
Therefore, the GCF of Fractions 76/190,81/382,136/561 is 1/20358690
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 190,382,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(190,382,561) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(190,382,561) x common factors =1 x 2 = 2
LCM(190,382,561) = ( 190 × 382 × 561 ) / 2
LCM(190,382,561) = 40717380 / 2
LCM(190,382,561) = 20358690
