The factors of 931 are 1, 7, 19, 49, 133, 931
The factors of 855 are 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
The HCF of 931,855 is 19.
Lets's calculate GCF of 931,855
19 | 931, 855 |
49, 45 |
∴ So the GCF of the given numbers is 19 = 19
Now, list down the factors of 931
:1,7,19,49,133,931
Now, list down the factors of 855
:1,3,5,9,15,19,45,57,95,171,285,855
Greatest Common Factor
We found the factors 931,855 . The biggest common factor number is the GCF number.
So the greatest common factor 931,855 is 19.
Lets's calculate LCM of 32,957
Given numbers has no common factors except 1. So, there LCM is their product i.e 30624
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 19/30624
Therefore, the GCF of Fractions 931/32,855/957 is 19/30624
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 32,957 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,957) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(32,957) x common factors =1 x 1 = 1
LCM(32,957) = ( 32 × 957 ) / 1
LCM(32,957) = 30624 / 1
LCM(32,957) = 30624
