1,2,5,10,971,1942,4855,9710
Greatest Common Factor
We found the factors 1780,9710 . The biggest common factor number is the GCF number.
So the greatest common factor 1780,9710 is 10.
Lets's calculate LCM of 57,561
3 | 57, 561 |
19, 187 |
∴ So the LCM of the given numbers is 3 x 19 x 187 = 10659
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/10659
Therefore, the GCF of Fractions 1780/57,9710/561 is 10/10659
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 57,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,561) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(57,561) x common factors =3 x 1 = 3
LCM(57,561) = ( 57 × 561 ) / 3
LCM(57,561) = 31977 / 3
LCM(57,561) = 10659
