Greatest Common Factor
We found the factors 46,83,17,75 . The biggest common factor number is the GCF number.
So the greatest common factor 46,83,17,75 is 1.
Lets's calculate LCM of 78,57,77,38
2 | 78, 57, 77, 38 |
3 | 39, 57, 77, 19 |
19 | 13, 19, 77, 19 |
13, 1, 77, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 19 x 13 x 1 x 77 x 1 = 114114
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/114114
Therefore, the GCF of Fractions 46/78,83/57,17/77,75/38 is 1/114114
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 78,57,77,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,57,77,38) = 1
common factors(in case of two or more numbers have common factors) = 114
GCF(78,57,77,38) x common factors =1 x 114 = 114
LCM(78,57,77,38) = ( 78 × 57 × 77 × 38 ) / 114
LCM(78,57,77,38) = 13008996 / 114
LCM(78,57,77,38) = 114114
