To be a multiple of 4, 10 and 20 the number must be a multiple of their lowest common multiple.

lcm(4, 10, 20) = 20

What is required is a multiple of 20 between 61 and 107. The numbers 80 and 100 both satisfy the problem of being between 61 and 107 and being a multiple of 4, 10 and 20.

For lack of support for multiple levels of exponentiation, I'll use "^" as an additional symbof for exponentiation. 1 crore is 10 million, or 107. Therefore, crorecrore = (107)10^7 = 107x10^7. The expression in the exponent (7 x 107) is the number of zeroes.
