Question

Find the G.C.D. of 1.08, 0.36 and 0.9

Answer 1

Given numbers are 1.08, 0.36 and 0.9

So firsty find the GCD od 108, 36 and 90

108 = 2×2×3×3×3

36 = 2×2×3×3

90 = 2×3×3×5

So GCD of 108, 36 and 9 is 2×3×3 = 18

Hence GCD of 1.08, 0.36 and 0.9 is 0.18

Answer 2

Given :

1.08 ; 0.36 and 0.9

To find :

G.C.D

Solution :

The G.C.D i.e greatest common divisor  is the HCF i.e highest common factor

The 1.08 ; 0.36 and 0.9

We can write

108 = $2\times 2\times 3 \times 3 \times 3$

36 = $2\times 2\times 3 \times 3$

90 = $2\times 3\times 3 \times 5$

So the common factors among three numbers are 2, 3 and 3

If we multiplied these three digits so the value comes 18 and the same is to be considered

Hence, the GCD of 1.08, 0.36 and 0.9 is 18
