3 and 41
1 and 123 or 2 and 61.5 or 3 and 41 or 4 and 30.75 etc
With 123 digits you can make 123 one-digit numbers.
When multiplied together, 3 and 41 equal 123.
To calculate manually if any number is a prime number, divide the number by ascending prime numbers until you reach the square root of the number. In this instance: 123/2 = 61.5 123/3 = 41 Therefore, 123 is not a prime number. However, since the first two factors we discovered are both prime - those being 3 and 41, it must not have any other factors.

41 x 3 = 123, Quite basic actually.
3 x 41
41 x 3
3*41 = 123.
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.
