Lets's calculate LCM of 680,940
2 | 680, 940 |
2 | 340, 470 |
5 | 170, 235 |
34, 47 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 34 x 47 = 31960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/31960
Therefore, the GCF of Fractions 6930/680,8985/940 is 15/31960
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 680,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,940) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(680,940) x common factors =20 x 1 = 20
LCM(680,940) = ( 680 × 940 ) / 20
LCM(680,940) = 639200 / 20
LCM(680,940) = 31960
