1,97
Greatest Common Factor
We found the factors 68,90,91,97 . The biggest common factor number is the GCF number.
So the greatest common factor 68,90,91,97 is 1.
Lets's calculate LCM of 62,93,14,459
2 | 62, 93, 14, 459 |
3 | 31, 93, 7, 459 |
31 | 31, 31, 7, 153 |
1, 1, 7, 153 |
∴ So the LCM of the given numbers is 2 x 3 x 31 x 1 x 1 x 7 x 153 = 199206
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/199206
Therefore, the GCF of Fractions 68/62,90/93,91/14,97/459 is 1/199206
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 62,93,14,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,93,14,459) = 1
common factors(in case of two or more numbers have common factors) = 186
GCF(62,93,14,459) x common factors =1 x 186 = 186
LCM(62,93,14,459) = ( 62 × 93 × 14 × 459 ) / 186
LCM(62,93,14,459) = 37052316 / 186
LCM(62,93,14,459) = 199206
