Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Greatest Common Factor
We found the factors 81,69,32,76 . The biggest common factor number is the GCF number.
So the greatest common factor 81,69,32,76 is 1.
Lets's calculate LCM of 27,82,86,72
2 | 27, 82, 86, 72 |
3 | 27, 41, 43, 36 |
3 | 9, 41, 43, 12 |
3, 41, 43, 4 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 3 x 41 x 43 x 4 = 380808
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/380808
Therefore, the GCF of Fractions 81/27,69/82,32/86,76/72 is 1/380808
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 27,82,86,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,82,86,72) = 1
common factors(in case of two or more numbers have common factors) = 36
GCF(27,82,86,72) x common factors =1 x 36 = 36
LCM(27,82,86,72) = ( 27 × 82 × 86 × 72 ) / 36
LCM(27,82,86,72) = 13709088 / 36
LCM(27,82,86,72) = 380808
