So the greatest common factor 47,72,36,26 is 1.
Lets's calculate LCM of 64,87,94,64
2 | 64, 87, 94, 64 |
2 | 32, 87, 47, 32 |
2 | 16, 87, 47, 16 |
2 | 8, 87, 47, 8 |
2 | 4, 87, 47, 4 |
2 | 2, 87, 47, 2 |
1, 87, 47, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 2 x 1 x 87 x 47 x 1 = 261696
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/261696
Therefore, the GCF of Fractions 47/64,72/87,36/94,26/64 is 1/261696
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 64,87,94,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,87,94,64) = 1
common factors(in case of two or more numbers have common factors) = 128
GCF(64,87,94,64) x common factors =1 x 128 = 128
LCM(64,87,94,64) = ( 64 × 87 × 94 × 64 ) / 128
LCM(64,87,94,64) = 33497088 / 128
LCM(64,87,94,64) = 261696
