:1,2,3,6,11,13,22,26,33,39,66,78,143,286,429,858
Greatest Common Factor
We found the factors 17,701,858 . The biggest common factor number is the GCF number.
So the greatest common factor 17,701,858 is 1.
Lets's calculate LCM of 20,36,692
2 | 20, 36, 692 |
2 | 10, 18, 346 |
5, 9, 173 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 9 x 173 = 31140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31140
Therefore, the GCF of Fractions 17/20,701/36,858/692 is 1/31140
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 20,36,692 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(20,36,692) = 4
common factors(in case of two or more numbers have common factors) = 4
GCF(20,36,692) x common factors =4 x 4 = 16
LCM(20,36,692) = ( 20 × 36 × 692 ) / 16
LCM(20,36,692) = 498240 / 16
LCM(20,36,692) = 31140
