Answer:
5(15+4)
Step-by-step explanation:
The greatest common factor is the greatest number that will divide two values. We have two values 75 and 20. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:
75: 1,3,5,15,25, 75
20: 1, 2, 4, 5, 10, 20
Both have 5 and this is the GCF. So we write the expression int he form 5(___+___). We divide each term by 5 to find the corresponding factor.
75/5= 15
20/5=4
5(15+4)
