Lets's calculate LCM of 920,124
2 | 920, 124 |
2 | 460, 62 |
230, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 230 x 31 = 28520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28520
Therefore, the GCF of Fractions 991/920,819/124 is 1/28520
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 920,124 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(920,124) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(920,124) x common factors =4 x 1 = 4
LCM(920,124) = ( 920 × 124 ) / 4
LCM(920,124) = 114080 / 4
LCM(920,124) = 28520
