Respuesta :
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
The GCF of numbers is the greatest common factor between the numbers.
- The GCF of the numbers is 4
- The expression as the product of their GCF is 4 x 23
The expression is given as:
[tex]\mathbf{64 + 28}[/tex]
(a) The GCF of the numbers
The numbers are 64 and 28
The factors are:
[tex]\mathbf{64 = 2 \times 2 \times 2 \times 2 \times 2 \times 2}[/tex]
[tex]\mathbf{28 = 2 \times 2 \times 7}[/tex]
So, the GCF is:
[tex]\mathbf{GCF = 2 \times 2}[/tex]
[tex]\mathbf{GCF = 4}[/tex]
The GCF of the numbers is 4
(b) The product of their GCF
[tex]\mathbf{64 + 28}[/tex]
Express as sum of products
[tex]\mathbf{64 + 28 = 4 \times 16 + 4 \times 7}[/tex]
Factor out 4
[tex]\mathbf{64 + 28 = 4 \times (16 + 7)}[/tex]
Add 16 and 7
[tex]\mathbf{64 + 28 = 4 \times 23}[/tex]
Hence, the expression as the product of their GCF is 4 x 23
