Answer :
To find the Greatest Common Factor (G.C.F) of 28, 42, and 56, we need to determine the largest number that divides all three numbers without leaving a remainder. Here's how you can find it step-by-step:
List the factors of each number:
- Factors of 28: 1, 2, 4, 7, 14, 28
- Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42
- Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
Identify the common factors:
The common factors of 28, 42, and 56 are 1, 2, 7, and 14.Select the greatest common factor:
Among the common factors, 14 is the largest. So, the G.C.F of 28, 42, and 56 is 14.
For the expression 15750 x 200, here is the step to solve it:
Multiply the numbers:
[tex]15750 \times 200 = 15750 \times (2 \times 100) = (15750 \times 2) \times 100[/tex]
This gives:
[tex]31500 \times 100 = 3150000[/tex]
Thus, the result of the multiplication 15750 x 200 is 3,150,000.
