It is: 6

It is: 90

2 x 32 x 5 = 90

90 = 2*3*3*5 150 = 2*3*5*5

Negative numbers don't have prime factorizations.

The prime factorizations are: 5 3 * 3 * 2 2 * 5 Eliminating the common factors, we get 3 * 3 * 2 * 5 Simplifying gives us 90 The LCM of 5, 18, and 10 is 90.

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 gcf of 27, 45, 63 and 90 is 18 Hope It Helps:)

Prime factorisation of 18 = 2*3*3 Prime factorisation of 30 = 2*3*5 Then 1/18 = 5*1/5*18 = 5*90 (using the prime factor of 30 that is not in 18) and 1/30 = 3*1/3*30 = 3*90 (using the extra prime factor of 18 that is not in 30) So 1/18 + 1/30 = 5/90 + 3/90 = 8/90 = 4/45

8: 2 12: 2, 3 27: 3 90: 2, 3, 5

Factors of 27: 1, 3, 9, 27 Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 GCF (27, 90) = 9

Prime factor each number. Collect the factors that are common. Multiply the numbers together and get it. 90=2x5x3x3 27=3x3x3 3x3=9
