Greatest Common Factor
We found the factors 212,129 . The biggest common factor number is the GCF number.
So the greatest common factor 212,129 is 1.
Lets's calculate LCM of 522,780
2 | 522, 780 |
3 | 261, 390 |
87, 130 |
∴ So the LCM of the given numbers is 2 x 3 x 87 x 130 = 67860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67860
Therefore, the GCF of Fractions 212/522,129/780 is 1/67860
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 522,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(522,780) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(522,780) x common factors =6 x 1 = 6
LCM(522,780) = ( 522 × 780 ) / 6
LCM(522,780) = 407160 / 6
LCM(522,780) = 67860
