7, 14 and 21
To determine what number goes into 9, 7, and 4, we need to find the greatest common factor (GCF) of these numbers. The GCF is the largest number that divides evenly into all three numbers. In this case, the GCF of 9, 7, and 4 is 1, as there are no common factors other than 1 that divide evenly into all three numbers.
If the GCF of two numbers p and q is 7, then the GCF of p2 and q2 is 14.
To determine what number goes into 5, 7, and 8, we need to find the greatest common factor (GCF) of these three numbers. The GCF is the largest number that divides evenly into all three numbers. In this case, the GCF of 5, 7, and 8 is 1, as there are no common factors other than 1 among these numbers. Therefore, the number that goes into 5, 7, and 8 is 1.
It would be possible to find two numbers whose sum is 7, two others whose difference is 7,two others whose product is 7, and two others whose quotient is 7.But if you're looking for numbers that equal 7, then 7 is your only choice.
