Greatest Common Factor
We found the factors 81,95,675 . The biggest common factor number is the GCF number.
So the greatest common factor 81,95,675 is 1.
Lets's calculate LCM of 62,533,642
2 | 62, 533, 642 |
31, 533, 321 |
∴ So the LCM of the given numbers is 2 x 31 x 533 x 321 = 10607766
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10607766
Therefore, the GCF of Fractions 81/62,95/533,675/642 is 1/10607766
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 62,533,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,533,642) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(62,533,642) x common factors =1 x 2 = 2
LCM(62,533,642) = ( 62 × 533 × 642 ) / 2
LCM(62,533,642) = 21215532 / 2
LCM(62,533,642) = 10607766
