Greatest Common Factor
We found the factors 1,72,10,987 . The biggest common factor number is the GCF number.
So the greatest common factor 1,72,10,987 is 1.
Lets's calculate LCM of 10,69,238,700
2 | 10, 69, 238, 700 |
5 | 5, 69, 119, 350 |
7 | 1, 69, 119, 70 |
1, 69, 17, 10 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 1 x 69 x 17 x 10 = 821100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/821100
Therefore, the GCF of Fractions 1/10,72/69,10/238,987/700 is 1/821100
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 10,69,238,700 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,69,238,700) = 1
common factors(in case of two or more numbers have common factors) = 140
GCF(10,69,238,700) x common factors =1 x 140 = 140
LCM(10,69,238,700) = ( 10 × 69 × 238 × 700 ) / 140
LCM(10,69,238,700) = 114954000 / 140
LCM(10,69,238,700) = 821100
