Greatest Common Factor
We found the factors 72,37,90,67 . The biggest common factor number is the GCF number.
So the greatest common factor 72,37,90,67 is 1.
Lets's calculate LCM of 88,16,39,647
2 | 88, 16, 39, 647 |
2 | 44, 8, 39, 647 |
2 | 22, 4, 39, 647 |
11, 2, 39, 647 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 2 x 39 x 647 = 4441008
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4441008
Therefore, the GCF of Fractions 72/88,37/16,90/39,67/647 is 1/4441008
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 88,16,39,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,16,39,647) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(88,16,39,647) x common factors =1 x 8 = 8
LCM(88,16,39,647) = ( 88 × 16 × 39 × 647 ) / 8
LCM(88,16,39,647) = 35528064 / 8
LCM(88,16,39,647) = 4441008
