Greatest Common Factor
We found the factors 87,31,771 . The biggest common factor number is the GCF number.
So the greatest common factor 87,31,771 is 1.
Lets's calculate LCM of 693,159,145
3 | 693, 159, 145 |
231, 53, 145 |
∴ So the LCM of the given numbers is 3 x 231 x 53 x 145 = 5325705
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5325705
Therefore, the GCF of Fractions 87/693,31/159,771/145 is 1/5325705
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 693,159,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(693,159,145) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(693,159,145) x common factors =1 x 3 = 3
LCM(693,159,145) = ( 693 × 159 × 145 ) / 3
LCM(693,159,145) = 15977115 / 3
LCM(693,159,145) = 5325705
