:1,2,3,4,6,12,31,62,93,124,186,372
Greatest Common Factor
We found the factors 31,19,372 . The biggest common factor number is the GCF number.
So the greatest common factor 31,19,372 is 1.
Lets's calculate LCM of 505,817,903
43 | 505, 817, 903 |
505, 19, 21 |
∴ So the LCM of the given numbers is 43 x 505 x 19 x 21 = 8664285
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8664285
Therefore, the GCF of Fractions 31/505,19/817,372/903 is 1/8664285
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 505,817,903 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,817,903) = 1
common factors(in case of two or more numbers have common factors) = 43
GCF(505,817,903) x common factors =1 x 43 = 43
LCM(505,817,903) = ( 505 × 817 × 903 ) / 43
LCM(505,817,903) = 372564255 / 43
LCM(505,817,903) = 8664285
