What is the smallest odd number and the largest even number with about three in two digits

The minimum odd number of divisor 3 is 15 and the maximum even number is 96~

If an odd number minus its largest divisor is 4740, what is the odd number?

a-a/(m+1)=4740
a=4740(m+1)/m
Because a is odd, m should be divisible by a and the quotient is odd,
4740=2*2*3*5*79,m=20,60,
And because a / (M + 1) is the largest divisor, M + 1 should be prime,
21 is a composite number, so m = 60,
a=4819

For an odd number, the sum of its largest divisor and the second approximate number is 60. What is the odd number
