Greatest Common Factor
We found the factors 98,76,79,72 . The biggest common factor number is the GCF number.
So the greatest common factor 98,76,79,72 is 1.
Lets's calculate LCM of 52,68,89,650
2 | 52, 68, 89, 650 |
2 | 26, 34, 89, 325 |
13 | 13, 17, 89, 325 |
1, 17, 89, 25 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 1 x 17 x 89 x 25 = 1966900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1966900
Therefore, the GCF of Fractions 98/52,76/68,79/89,72/650 is 1/1966900
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 52,68,89,650 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(52,68,89,650) = 1
common factors(in case of two or more numbers have common factors) = 104
GCF(52,68,89,650) x common factors =1 x 104 = 104
LCM(52,68,89,650) = ( 52 × 68 × 89 × 650 ) / 104
LCM(52,68,89,650) = 204557600 / 104
LCM(52,68,89,650) = 1966900
