1. Factors of 30 are numbers that, when multiplied in pairs give the product as 30. There are overall 8 factors of 30 among which 30 is the biggest factor and 1, 2, 3, 5, 6, 10, 15, and 30 are positive factors. The sum of all factors of 30 is 72. Its Prime Factors are 1, 2, 3, 5, 6, 10, 15, 30 and (1, 30), (2, 15), (3, 10) and (5, 6) are Pair Factors.
Factors of 30: 1, 2, 3, 5, 6, 10, 15 and 30
Negative Factors of 30: -1, -2, -3, -5, -6, -10, -15 and -30
Prime Factors of 30: 2, 3, 5
Prime Factorization of 30: 2 × 3 × 5 = 2 × 3 × 5
Sum of Factors of 30: 72
2.Therefore, 42 can be expressed as a product of its prime factors as 2 × 3 × 7.
3.The prime factors of 143 are 11 and 13. 11 × 13 = 143.
Step-by-step explanation:
The factors of 30 are all the integers that 30 can be divided into. The number 30 is an even composite number. A number is said to be composite if it has more than two factors. Since it is even, it will have 2 as a factor. Thus, by understanding the properties of the number 30, we can find the factors of 30 which are 1, 2, 3, 5, 6, 10, 15, and 30.
