What is the smallest number that appears in both rows this number is said to be the least common multiples of 2 and 3

The least common multiples of 2 and 3 would be 2 and 1 also 2 and is at its lowest multiple

Iam pretty sure its a sorry if im wrong

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)
