12.6 + 3.1 + 5.1 = 20.8
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.
the "sum" means to add the numbers, therefore:98 + 126 = 224
31 is prime, but 51 is not as 51=3*17.

Expressed as a percentage, 51/126 x 100 = 40.476190 recurring (that is, 40.476190476190..) percent.
Is the sum 31
31 is prime, but 51 is not as 51=3*17.
730.
Yes, but only if one is negative, For example, -31/2 and 51/2.
The LCM of 31 and 51 is 1,581.
