what is the hcf of 5.2 ,13 ,39 , my ans is 1.3 but somewhere ans is given 2.6

Question

Answer 1

First, convert decimals into fractions
52/10, 13, 39
Now, HCF of fractions is given by,
H.C.F of numerators / L.C.M of denominators
H.C.F of numerators = 13; L.C.M of denominators=10
Hence, H.C.F of numerators / L.C.M of denominators = 13/10
=1.3
Hence, 1.3 is the correct answer.

Answer 2

First, convert decimals into fractions
52/10, 13, 39
Now, HCF of fractions is given by,
H.C.F of numerators / L.C.M of denominators
H.C.F of numerators = 13; L.C.M of denominators=10
Hence, H.C.F of numerators / L.C.M of denominators = 13/10
=1.3
Hence, 1.3 is the correct answer.
