Expressed as a mixed number in its simplest form, 71/42 is equal to 1 29/42 or one and twenty-nine forty-secondths.
42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
35/42 + 36/42 = 71/42 = 1 and 29/42

42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
It is: 21*31*71 = 42
35/42 + 36/42 = 71/42 = 1 and 29/42
I would estimate 29.
The GCF is 1.
