Greatest Common Factor
We found the factors 83,60,63,67 . The biggest common factor number is the GCF number.
So the greatest common factor 83,60,63,67 is 1.
Lets's calculate LCM of 63,91,86,91
7 | 63, 91, 86, 91 |
13 | 9, 13, 86, 13 |
9, 1, 86, 1 |
∴ So the LCM of the given numbers is 7 x 13 x 9 x 1 x 86 x 1 = 70434
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/70434
Therefore, the GCF of Fractions 83/63,60/91,63/86,67/91 is 1/70434
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 63,91,86,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,91,86,91) = 1
common factors(in case of two or more numbers have common factors) = 637
GCF(63,91,86,91) x common factors =1 x 637 = 637
LCM(63,91,86,91) = ( 63 × 91 × 86 × 91 ) / 637
LCM(63,91,86,91) = 44866458 / 637
LCM(63,91,86,91) = 70434
