The factors of 21 are 1, 3, 7, and 21. The factors of 49 are 1, 7, and 49.
The factors of 7 are the numbers that can be multiplied together to result in 7. In this case, the factors of 7 are 1 and 7, as 1 x 7 = 7. Since 7 is a prime number, it only has two factors, which are 1 and 7.
2 and 3 and 7
It's not entirely clear from the wording of your question what it is you want to know. Seven is a one-digit number. The sum of its digits is 7. Seven has two factors: 1 and 7. That sum is 8.
As a product of its prime factors: 5*7*7 = 245
Factors that are the same for two or more numbers are their common factors.What numbers are factors of both 7 and 8?Factors of 7 are 1, and 7.Factors of 8 are 1, 2, 4, and 8.Common factors are the numbers that are in both lists.So, 1 is the common factor of 7 and 8.
two numbers that have factors of 2, 5 and 7 are 70 and 140.
The factors of 7 are 1 and 7. The factors of 21 are 1, 3, 7, and 21. The only numbers that are factors of BOTH 7 and 21 are 1 and 7.
Numbers with exactly 7 factors are of the form pqr, where p, q, and r are distinct prime numbers. To find numbers with 7 factors, you need to look for numbers that can be expressed as the product of three different prime numbers.
All numbers have factors. Some numbers have only two factors, the number one and the number itself. These are known as prime numbers. 7 has two factors: 1 and 7. 7 is a prime number.
Pairs of numbers whose sum is -14 and that are factors of -189 include -7 and -7, and -21 and 7.
