11, 31, 41, 61, 71
115 is greater than 71.
No it is not, you can test this by trying to divide 781 by all prime numbers (p) where p^2<=781. note that 11 divides 781 evenly, with a remainder of 71. 11 is prime, and the existing factors of 71 can be tested using the same method, p^2<=71. noting that 9^2>71, we know if 71 is not prime, a prime number less than 9 must divide it. and since 2, 3, 5, and 7 do not divide 71 that is also prime Thus 781 is not prime, and the factors of 781 are 11 and 71.
It is: 29+71 = 100
The number with 6 tens and 11 ones can be calculated by multiplying the number of tens by 10 and adding the number of ones. Therefore, 6 tens is 60 (6 x 10) and 11 ones is 11. Adding these together, 60 + 11 equals 71. Thus, the number is 71.
