So the greatest common factor 85,985,605 is 5.
Lets's calculate LCM of 81,88,936
2 | 81, 88, 936 |
2 | 81, 44, 468 |
2 | 81, 22, 234 |
3 | 81, 11, 117 |
3 | 27, 11, 39 |
9, 11, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 9 x 11 x 13 = 92664
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/92664
Therefore, the GCF of Fractions 85/81,985/88,605/936 is 5/92664
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 81,88,936 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,88,936) = 1
common factors(in case of two or more numbers have common factors) = 72
GCF(81,88,936) x common factors =1 x 72 = 72
LCM(81,88,936) = ( 81 × 88 × 936 ) / 72
LCM(81,88,936) = 6671808 / 72
LCM(81,88,936) = 92664
