So the greatest common factor 98,787,272 is 1.
Lets's calculate LCM of 15,54,757
3 | 15, 54, 757 |
5, 18, 757 |
∴ So the LCM of the given numbers is 3 x 5 x 18 x 757 = 204390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/204390
Therefore, the GCF of Fractions 98/15,787/54,272/757 is 1/204390
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 15,54,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,54,757) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(15,54,757) x common factors =1 x 3 = 3
LCM(15,54,757) = ( 15 × 54 × 757 ) / 3
LCM(15,54,757) = 613170 / 3
LCM(15,54,757) = 204390
