So the greatest common factor 714,1666 is 238.
Lets's calculate LCM of 697,986
17 | 697, 986 |
41, 58 |
∴ So the LCM of the given numbers is 17 x 41 x 58 = 40426
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 238/40426
Therefore, the GCF of Fractions 714/697,1666/986 is 238/40426
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 697,986 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(697,986) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(697,986) x common factors =17 x 1 = 17
LCM(697,986) = ( 697 × 986 ) / 17
LCM(697,986) = 687242 / 17
LCM(697,986) = 40426
