The factors of 989 are 1, 23, 43, 989
The HCF of 989,989 is 989.
Lets's calculate GCF of 989,989
23 | 989, 989 |
43 | 43, 43 |
1, 1 |
∴ So the GCF of the given numbers is 23 x 43 = 989
Now, list down the factors of 989
:1,23,43,989
Now, list down the factors of 989
:1,23,43,989
Greatest Common Factor
We found the factors 989,989 . The biggest common factor number is the GCF number.
So the greatest common factor 989,989 is 989.
Lets's calculate LCM of 712,986
2 | 712, 986 |
356, 493 |
∴ So the LCM of the given numbers is 2 x 356 x 493 = 351016
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 989/351016
Therefore, the GCF of Fractions 989/712,989/986 is 989/351016
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 712,986 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(712,986) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(712,986) x common factors =2 x 1 = 2
LCM(712,986) = ( 712 × 986 ) / 2
LCM(712,986) = 702032 / 2
LCM(712,986) = 351016
