1,3,9,19,57,171
Greatest Common Factor
We found the factors 85,21,19,171 . The biggest common factor number is the GCF number.
So the greatest common factor 85,21,19,171 is 1.
Lets's calculate LCM of 89,51,28,50
2 | 89, 51, 28, 50 |
89, 51, 14, 25 |
∴ So the LCM of the given numbers is 2 x 89 x 51 x 14 x 25 = 3177300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3177300
Therefore, the GCF of Fractions 85/89,21/51,19/28,171/50 is 1/3177300
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 89,51,28,50 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,51,28,50) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(89,51,28,50) x common factors =1 x 2 = 2
LCM(89,51,28,50) = ( 89 × 51 × 28 × 50 ) / 2
LCM(89,51,28,50) = 6354600 / 2
LCM(89,51,28,50) = 3177300
