Find the GCF of 18j plus 27

Answer 1

To find the greatest common factor (GCF) of 18j and 27, we need to factor both terms and find the highest power common between them.

The prime factorization of 18j is 2 * 3 * 3 * j.
The prime factorization of 27 is 3 * 3 * 3.

Looking at the prime factorizations, we can see that the highest power common to both terms is 3 * 3 = 9.

Therefore, the GCF of 18j and 27 is 9.

Answer 2

Find GCF of 42M -28n

Answer 3

To find the greatest common factor (GCF) of 42M and -28n, we need to factor both terms and find the highest power common between them.

The prime factorization of 42M is 2 * 3 * 7 * M.
The prime factorization of -28n is -1 * 2 * 2 * 7 * n.

Looking at the prime factorizations, we can see that the highest power common to both terms is 2 * 7 = 14.

Therefore, the GCF of 42M and -28n is 14.

Answer 4

Factor -27H +6 using GCF

Answer 5

To factor -27H + 6 using the greatest common factor (GCF), we need to find the highest power common between the terms.

The GCF of -27H and 6 is 3 because they have a common factor of 3. To factor out the GCF, we divide each term by 3:

(-27H + 6)/3 = -9H + 2

Therefore, -27H + 6 can be factored as 3(-9H + 2).

Answer 6

Answer 7

Simplify by combining like terms.

2/8x+3/10y−5/8x+4/10y

14/18xy
14 over 18 x y

−3/8x+7/10y
negative 3 eighths x plus 7 tenths y

7/10x+7/8y
7 tenths x plus 7 eighths y

4/18xy
