Greatest Common Factor
We found the factors 67,79,74,49 . The biggest common factor number is the GCF number.
So the greatest common factor 67,79,74,49 is 1.
Lets's calculate LCM of 68,71,75,774
2 | 68, 71, 75, 774 |
3 | 34, 71, 75, 387 |
34, 71, 25, 129 |
∴ So the LCM of the given numbers is 2 x 3 x 34 x 71 x 25 x 129 = 46710900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/46710900
Therefore, the GCF of Fractions 67/68,79/71,74/75,49/774 is 1/46710900
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 68,71,75,774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,71,75,774) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(68,71,75,774) x common factors =1 x 6 = 6
LCM(68,71,75,774) = ( 68 × 71 × 75 × 774 ) / 6
LCM(68,71,75,774) = 280265400 / 6
LCM(68,71,75,774) = 46710900
