Greatest Common Factor
We found the factors 62,917,140 . The biggest common factor number is the GCF number.
So the greatest common factor 62,917,140 is 1.
Lets's calculate LCM of 86,89,356
2 | 86, 89, 356 |
89 | 43, 89, 178 |
43, 1, 2 |
∴ So the LCM of the given numbers is 2 x 89 x 43 x 1 x 2 = 15308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15308
Therefore, the GCF of Fractions 62/86,917/89,140/356 is 1/15308
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 86,89,356 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,89,356) = 1
common factors(in case of two or more numbers have common factors) = 178
GCF(86,89,356) x common factors =1 x 178 = 178
LCM(86,89,356) = ( 86 × 89 × 356 ) / 178
LCM(86,89,356) = 2724824 / 178
LCM(86,89,356) = 15308
