The HCF of 278,276 is 2.
Lets's calculate GCF of 278,276
2 | 278, 276 |
139, 138 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 278
:1,2,139,278
Now, list down the factors of 276
:1,2,3,4,6,12,23,46,69,92,138,276
Greatest Common Factor
We found the factors 278,276 . The biggest common factor number is the GCF number.
So the greatest common factor 278,276 is 2.
Lets's calculate LCM of 215,102
Given numbers has no common factors except 1. So, there LCM is their product i.e 21930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/21930
Therefore, the GCF of Fractions 278/215,276/102 is 2/21930
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 215,102 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(215,102) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(215,102) x common factors =1 x 1 = 1
LCM(215,102) = ( 215 × 102 ) / 1
LCM(215,102) = 21930 / 1
LCM(215,102) = 21930
