Oh, isn't that a happy little question! Let's break down the number 90 into its prime factors. We can see that 90 is equal to 2 x 3 x 3 x 5. Each of these numbers is a prime factor, which means they can't be divided any further. Keep on painting those prime factors, my friend!
42 as a product of its prime factors is 2*3*7. 90 as a product of its prime factors is 2*3*3*5.
2 x 3 x 3 x 5 = 90
It is: 2*3 which is 6
The prime factors are: 2,3,5.
19 and 90 have no common prime factors.
The prime factors of 90 are: 2,3,5
As a product of its prime factors: 2*3*3*5 = 90
90 has three prime factors: 2, 3 and 5.
The prime factors of 18 are 2, 3, and 3. The prime factors of 90 are 2, 3, 3, and 5. The prime factors they have in common are 2, 3, and 3. Since 18 is a factor of 90, its prime factors will be the prime factors that the two numbers have in common.
The prime factor of 19 is 19. The prime factors of 90 are 2, 3 and 5.
The prime factors of 90 are: 2,3,5
The prime factors of 90 are 2,3,3,5.
No 3*30 =90 30 Is not a prime
The prime factors of 70 are 2, 5, and 7. The prime factors of 90 are 2, 3, 3, and 5. The prime factors that 70 and 90 have in common are 2 and 5. The greatest common factor of 70 and 90 is the product of the prime factors they have in common, so it is 2 x 5 = 10.
there are none, 19 is prime and it doesnt go into 90
