The factors of 154 are 1, 2, 7, 11, 14, 22, 77, 154
The factors of 861 are 1, 3, 7, 21, 41, 123, 287, 861
The HCF of 154,861 is 7.
Lets's calculate GCF of 154,861
7 | 154, 861 |
22, 123 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 154
:1,2,7,11,14,22,77,154
Now, list down the factors of 861
:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 154,861 . The biggest common factor number is the GCF number.
So the greatest common factor 154,861 is 7.
Lets's calculate LCM of 913,997
Given numbers has no common factors except 1. So, there LCM is their product i.e 910261
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/910261
Therefore, the GCF of Fractions 154/913,861/997 is 7/910261
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 913,997 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(913,997) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(913,997) x common factors =1 x 1 = 1
LCM(913,997) = ( 913 × 997 ) / 1
LCM(913,997) = 910261 / 1
LCM(913,997) = 910261
