Greatest Common Factor
We found the factors 89,77,257 . The biggest common factor number is the GCF number.
So the greatest common factor 89,77,257 is 1.
Lets's calculate LCM of 755,713,780
5 | 755, 713, 780 |
151, 713, 156 |
∴ So the LCM of the given numbers is 5 x 151 x 713 x 156 = 83977140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/83977140
Therefore, the GCF of Fractions 89/755,77/713,257/780 is 1/83977140
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 755,713,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(755,713,780) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(755,713,780) x common factors =1 x 5 = 5
LCM(755,713,780) = ( 755 × 713 × 780 ) / 5
LCM(755,713,780) = 419885700 / 5
LCM(755,713,780) = 83977140
