Math question: What is the sum of the digits in the number 2972?

To find the sum of the digits in 2972, we add the individual digits: 2 + 9 + 7 + 2 = 20.

Math question: What is the sum of the first 5 positive multiples of 2972? Explanation: To find the sum, we can use the formula for the sum of an arithmetic series. The first term, a, is 2972, and the common difference, d, is also 2972. The sum of the first n terms, Sn, can be calculated using the formula Sn = (n/2)(2a + (n-1)d). Plugging in the values, we get Sn = (5/2)(2*2972 + (5-1)*2972) = (5/2)(2*2972 + 4*2972) = (5/2)(2*2972 + 11888) = (5/2)(5944 + 11888) = (5/2)(17832) = 44680.

The sum of the first 5 positive multiples of 2972 is 44680.

Math question: What is the sum of all the prime factors of 2972?

To find the prime factors, we divide 2972 by the smallest prime number, 2, repeatedly until it is not divisible anymore. Doing this, we find the prime factors as 2, 2, 743. The sum of these prime factors is 2 + 2 + 743 = 747. Thus, the sum of all the prime factors of 2972 is 747.
