1,3,5,15,37,111,185,555
Greatest Common Factor
We found the factors 16,39,50,555 . The biggest common factor number is the GCF number.
So the greatest common factor 16,39,50,555 is 1.
Lets's calculate LCM of 17,68,80,78
2 | 17, 68, 80, 78 |
2 | 17, 34, 40, 39 |
17 | 17, 17, 20, 39 |
1, 1, 20, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 17 x 1 x 1 x 20 x 39 = 53040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/53040
Therefore, the GCF of Fractions 16/17,39/68,50/80,555/78 is 1/53040
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 17,68,80,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,68,80,78) = 1
common factors(in case of two or more numbers have common factors) = 136
GCF(17,68,80,78) x common factors =1 x 136 = 136
LCM(17,68,80,78) = ( 17 × 68 × 80 × 78 ) / 136
LCM(17,68,80,78) = 7213440 / 136
LCM(17,68,80,78) = 53040
