Greatest Common Factor
We found the factors 3,7,9,72 . The biggest common factor number is the GCF number.
So the greatest common factor 3,7,9,72 is 1.
Lets's calculate LCM of 62,98,31,945
2 | 62, 98, 31, 945 |
7 | 31, 49, 31, 945 |
31 | 31, 7, 31, 135 |
1, 7, 1, 135 |
∴ So the LCM of the given numbers is 2 x 7 x 31 x 1 x 7 x 1 x 135 = 410130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/410130
Therefore, the GCF of Fractions 3/62,7/98,9/31,72/945 is 1/410130
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 62,98,31,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,98,31,945) = 1
common factors(in case of two or more numbers have common factors) = 434
GCF(62,98,31,945) x common factors =1 x 434 = 434
LCM(62,98,31,945) = ( 62 × 98 × 31 × 945 ) / 434
LCM(62,98,31,945) = 177996420 / 434
LCM(62,98,31,945) = 410130
