Factors for 20 are: 1, 2, 4, 5, 10, 20
Prime Factors: 2, 5
sum of prime factors = 2 + 5 = 7
The factors of 91 are: 1 7 13 91.The prime factors are: 7 x 13The sum of the prime factors = 7 + 13 = 20
It is: 3+17 = 20
To find the sum of all prime numbers between 20 and 40, we first list out the prime numbers in that range: 23, 29, 31, 37. Then, we simply add them together: 23 + 29 + 31 + 37 = 120. Therefore, the sum of all prime numbers between 20 and 40 is 120.
1 + 2 + 4 = 7
