Prime factor each number and multiply all the numbers that are in both numbers. 30=2x3x5 85=5x17 5 is in both
They are: 83+2 = 85
41 43 47 53 59 61 67 71 73 79 83.
All prime numbers except for 2 are odd. The sum of any two odd numbers is even. Therefore, unless 85 is prime (it's not) or -2 is, (it's not) there aren't two prime numbers that will equal 87.
85
Numbers can't have prime numbers, some numbers are prime numbers. Prime numbers are numbers that have no factors other than 1 and itself. 85 is not a prime number because its factors are 1, 5, 17, and 85.
If you mean: 36 74 40 23 and 85 then they are all composite numbers except for 23 which is a prime number because it has only two factors which are itself and one
As a product of its prime factors: 5*17 = 85
Prime factor each number and multiply all the numbers that are in both numbers. 30=2x3x5 85=5x17 5 is in both
All of them except for 89 which is a prime number
They are: 83+2 = 85
5 x 17 = 85
No.
