So the greatest common factor 324,140 is 4.
Lets's calculate LCM of 692,440
2 | 692, 440 |
2 | 346, 220 |
173, 110 |
∴ So the LCM of the given numbers is 2 x 2 x 173 x 110 = 76120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/76120
Therefore, the GCF of Fractions 324/692,140/440 is 4/76120
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 692,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(692,440) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(692,440) x common factors =4 x 1 = 4
LCM(692,440) = ( 692 × 440 ) / 4
LCM(692,440) = 304480 / 4
LCM(692,440) = 76120
