The factors of 151 are 1, 151
The factors of 657 are 1, 3, 9, 73, 219, 657
The HCF of 151,657 is 1.
Lets's calculate GCF of 151,657
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 151
:1,151
Now, list down the factors of 657
:1,3,9,73,219,657
Greatest Common Factor
We found the factors 151,657 . The biggest common factor number is the GCF number.
So the greatest common factor 151,657 is 1.
Lets's calculate LCM of 217,170
Given numbers has no common factors except 1. So, there LCM is their product i.e 36890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36890
Therefore, the GCF of Fractions 151/217,657/170 is 1/36890
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 217,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(217,170) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(217,170) x common factors =1 x 1 = 1
LCM(217,170) = ( 217 × 170 ) / 1
LCM(217,170) = 36890 / 1
LCM(217,170) = 36890
