2 x 2 x 3 x 7
7 and 12
The sum of 72 and 12 is 84. The product of the two numbers is 864.
Let the numbers be 'n' & '3n' Hence their sum is n + 3n = 84 4n = 84 n = 21 & 3n = 63 ( 3 x 21)
The sum of a number x and 84
606
The twin primes 41 + 43 = 84.
The sum of 622 and 84 is 706.
2 x 2 x 3 x 7 = 84
In the problem 56 + 28 = 84, 84 is the sum.
If two prime number have a sum of 54 they cannot have a sum of 84, and conversely.
