Question

Find the sum of all the divisors of the sum of the highest divisor of 39
and the lowest divisor of 27.​
1) 80 (2) 90 (3) 100 (4 )89​

Answer 1

The sum of the all divisor of the sum of the highest divisor of 39 and the lowest divisor of 27 would be 90

Highest divisor of 39 would be 39 itself

and lowest divisor of 27 would be 1

The sum of these two numbers would be 39+1 = 40

Divisors of 40 are:

1,2,4,5,8,10,20,40

Sum of all these divisors would be 1+2+4+5+8+10+20+40 = 90
