3 X 41
two numbers which are equal to 123:123 + 0122 + 1121 + 2120 + 3 ...
They are 61+62 = 123
65 + 58 = 123 65 - 58 = 7 The two numbers are therefore 58 and 65.
3 and 41
3 X 41
41 x 3 = 123, Quite basic actually.

65 + 58 = 123 65 - 58 = 7 The two numbers are therefore 58 and 65.
3 and 41
When multiplied together, 3 and 41 equal 123.
3 and 41
There is no such pair.
120 and 3.
There is no pair of prime numbers that sum to 123.Proof :Any two odd primes will sum to an even number, thus excluding 123 which is odd.Since 2 is the only even prime, the only possible solution is 2 + 121 = 123.But, 121 is not prime because it is 11 x 11.A similar proof shows that there is no pair of primes whose difference is 123.There are two primes that multiply to 123 : - 3 and 41.
Suppose the smaller number is x, then the bigger number is x+7 Their sum is 123 ie x + (x+7) = 123 or 2x + 7 = 123 or 2x = 123 - 7 = 116 so that x = 58 and then x+7 = 65 The two numbers are 58 and 65
