2x21x11
Three ways (I think).
2+3,11+3,3+17
231 = 3 x 7 x 11
Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.
2x21x11
Three ways (I think).
2+3,11+3,3+17
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
A number as a product of prime numbers would be "x".
231 = 3 x 7 x 11
Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.
567576657675756765
That's called the prime factorization.
Prime factorization of 27 = 3x3x3
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
Its impossible, there are only 5 single digit numbers that are not prime
