Lets's calculate LCM of 824,680
2 | 824, 680 |
2 | 412, 340 |
2 | 206, 170 |
103, 85 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 103 x 85 = 70040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/70040
Therefore, the GCF of Fractions 279/824,9138/680 is 3/70040
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 824,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(824,680) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(824,680) x common factors =8 x 1 = 8
LCM(824,680) = ( 824 × 680 ) / 8
LCM(824,680) = 560320 / 8
LCM(824,680) = 70040
