The factors of 202 are 1, 2, 101, 202
The HCF of 172,202 is 2.
Lets's calculate GCF of 172,202
2 | 172, 202 |
86, 101 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 172
:1,2,4,43,86,172
Now, list down the factors of 202
:1,2,101,202
Greatest Common Factor
We found the factors 172,202 . The biggest common factor number is the GCF number.
So the greatest common factor 172,202 is 2.
Lets's calculate LCM of 715,239
Given numbers has no common factors except 1. So, there LCM is their product i.e 170885
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/170885
Therefore, the GCF of Fractions 172/715,202/239 is 2/170885
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 715,239 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,239) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(715,239) x common factors =1 x 1 = 1
LCM(715,239) = ( 715 × 239 ) / 1
LCM(715,239) = 170885 / 1
LCM(715,239) = 170885
