The way you are asked to do this is not very convenient. 91=7*13 and 35=7*5.

Multiple_____Value_____Value
1____________91_________35
2____________182________70
3____________273________105
4____________364________140
5____________455________175

this becomes tiring very quickly.

Why not just examine the factorizations? You need 5%2A7%2A13=highlight%28455%29 which is 35*9 and 91*5.

Larger number:                   91

Smallest MULTIPLE of 91:         91 x 1 = 91  (NOT a MULTIPLE of smaller number, or 35)

Second smallest MULTIPLE of 91:  91 x 2 = 182 (NOT a MULTIPLE of smaller number, or 35)

Third smallest MULTIPLE of 91:   91 x 3 = 273 (NOT a MULTIPLE of smaller number, or 35)

Fourth smallest MULTIPLE of 91:  91 x 4 = 364 (NOT a MULTIPLE of smaller number, or 35)

Fifth smallest MULTIPLE of 91:   91 x 5 = 455 (IS a MULTIPLE of smaller number, or 35)
