1,2,4,7,8,14,16,19,28,38,56,76,112,133,152,266,304,532,1064,2128
Greatest Common Factor
We found the factors 699,2128 . The biggest common factor number is the GCF number.
So the greatest common factor 699,2128 is 1.
Lets's calculate LCM of 880,445
5 | 880, 445 |
176, 89 |
∴ So the LCM of the given numbers is 5 x 176 x 89 = 78320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78320
Therefore, the GCF of Fractions 699/880,2128/445 is 1/78320
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 880,445 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(880,445) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(880,445) x common factors =5 x 1 = 5
LCM(880,445) = ( 880 × 445 ) / 5
LCM(880,445) = 391600 / 5
LCM(880,445) = 78320
