Question

find the gretest number that will divide 517 and 815 leaving the remainder 1 and 3 respectively​

Answer 1

Answer:

Ans is 4

Step-by-step explanation:

If we get remainder of 517 be 1,

Let n1=517-1=516

Same wise n2=815-3=812

The factors of 516 are 1,2,3,4,6,12,43,86,129,172,258,516

The factors of 812 are

1,2,4,7,14,28,29,58,116,203,406,812

The common factors are 2,4

When 517,815 divided by 2 we get remainder of 1,1

When 517,815 divided by 4 we get remainder of 1,3 respectively as given in question

So ans is 4
