Of course the primes cannot be unique since 2x3x5x7=210>84.

The answer is 2x2x3x7.

No prime numbers equal 84. The only number equal to 84 is 84,and it isn't a prime number.The prime factors of 84 are: 1, 2, 2, 3, and 7

As a product of its prime factors: 2*2*3*7 = 84

because when you multiply 2x2 it =4 then you multiply 4x3=12 then you multiply 12x7=wich you will have your answer 84!

The prime factors of 84 are 2, 2, 3, and 7.

84 and 91 are composite numbers 67 and 73 are prime numbers

9.165151389911680013176094387456 Solution: n * n = 84 n ^2 = 84 n = sqrt (84) n = 9.165151389911680013176094387456 check: 9.165151389911680013176094387456^2 = 84 = true! If you don't mean the square root of 84, then there are a number of numbers you can multiply to get 84, such as these: 42 * 2 28 * 3 21 * 4 14 * 6 7 * 12

No. In order for two factors (i.e. two numbers multiplied together) to result in an even number, at least one of the factors must be even. Except for "2" all prime numbers by definition must be odd numbers. 168/2 = 84. 84 is not prime. Therefore you are looking for 2 odd factors of 168. But this is a fruitless search as 2 odd numbers multiplied together will never result in an even number.

56 and 84 are both composite numbers, so neither are prime and they are not relatively prime either as they share several factors.

x/1 + x/x = 84 where x = a prime number that is divisible by 1 and itself. Then find common denominator of 1x. Then we have x squared/1x + x/1x = 84. To simplify this will be x squared + x/1x = 84. The this becomes 1 + x = 84. Then x = 83. The prime numbers are 1 and 83 which fit the equation.
