The factors of 258 are 1, 2, 3, 6, 43, 86, 129, 258
The HCF of 538,258 is 2.
Lets's calculate GCF of 538,258
2 | 538, 258 |
269, 129 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 538
:1,2,269,538
Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Greatest Common Factor
We found the factors 538,258 . The biggest common factor number is the GCF number.
So the greatest common factor 538,258 is 2.
Lets's calculate LCM of 85,764
Given numbers has no common factors except 1. So, there LCM is their product i.e 64940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/64940
Therefore, the GCF of Fractions 538/85,258/764 is 2/64940
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 85,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,764) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(85,764) x common factors =1 x 1 = 1
LCM(85,764) = ( 85 × 764 ) / 1
LCM(85,764) = 64940 / 1
LCM(85,764) = 64940
