List of positive integer factors of 35 that divides 35 without a remainder.
1,5,7,35
Greatest Common Factor
We found the factors 81,74,89,35 . The biggest common factor number is the GCF number.
So the greatest common factor 81,74,89,35 is 1.
Lets's calculate LCM of 66,77,72,37
2 | 66, 77, 72, 37 |
3 | 33, 77, 36, 37 |
11 | 11, 77, 12, 37 |
1, 7, 12, 37 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 1 x 7 x 12 x 37 = 205128
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/205128
Therefore, the GCF of Fractions 81/66,74/77,89/72,35/37 is 1/205128
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 66,77,72,37 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,77,72,37) = 1
common factors(in case of two or more numbers have common factors) = 66
GCF(66,77,72,37) x common factors =1 x 66 = 66
LCM(66,77,72,37) = ( 66 × 77 × 72 × 37 ) / 66
LCM(66,77,72,37) = 13538448 / 66
LCM(66,77,72,37) = 205128
