What did you do to the obtained GCF of the numerical coefficients and the GCF of the variables? in ur opinion ty

Find all factors that the numbers have in common. You can also determine the GCF if you have both numbers and variables. Factorize the numbers and identify all common factors. To get the GCF multiply all common factors.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
