List of positive integer factors of 67 that divides 67 without a remainder.
1,67
Greatest Common Factor
We found the factors 89,11,49,67 . The biggest common factor number is the GCF number.
So the greatest common factor 89,11,49,67 is 1.
Lets's calculate LCM of 67,85,20,751
5 | 67, 85, 20, 751 |
67, 17, 4, 751 |
∴ So the LCM of the given numbers is 5 x 67 x 17 x 4 x 751 = 17107780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17107780
Therefore, the GCF of Fractions 89/67,11/85,49/20,67/751 is 1/17107780
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 67,85,20,751 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,85,20,751) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(67,85,20,751) x common factors =1 x 5 = 5
LCM(67,85,20,751) = ( 67 × 85 × 20 × 751 ) / 5
LCM(67,85,20,751) = 85538900 / 5
LCM(67,85,20,751) = 17107780
