Two numbers are relatively prime if and only if they share no common proper factors (other than 1, which is a factor of all numbers). The factors of 4 are 4 and 2, while 7 has no factors other than 1 and itself. Since 4 and 7 have none of the same proper factors, they are relatively prime.

'4' is NOT a prime , because it is the product of 2 x 2 = 4
'7' is IS a prime , as it has not factors.

Are 64 and 144 relatively prime?
No, 64 and 144 are not relatively prime. To be relatively prime, the only common factor they could have would be 1. They have other common factors such as 2, 4, 8 and 16.
How do you find relatively prime?
If two or more factors are relatively prime, then they only have 1 as a common factor. Take 7 and 9 for example. The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9
Is 7 relatively prime?
In order to answer a question about relative primeness, you need to talk about two or more numbers. The question only asked about 1. Please restate the question.7 is relatively prime to all the integers which can not be divide by 7.
What are a pair of numbers that are relatively prime?
Two numbers which are "relatively prime" have no common prime factors. To illustrate, let's write several numbers in terms of their prime factors: 24 = 2 x 2 x 2 x 3 25 = 5 x 5 42 = 2 x 3 x 7 70 = 2 x 5 x 7 You can see that 24 and 25 are relatively prime, because they don't share any common prime factors. Likewise, 25 and 42 are relatively prime. 24 and 42, however, are NOT relatively prime because they share the common factors of 2 and 3. Likewise 25 and 70 are NOT relatively prime because they share the common factor 5. When a fraction is in its simplest form, the numerator and denominator are relatively prime.
Are 22 and 64 relatively prime?
22 is not relatively prime
Are 7 and 13 relatively prime?
Yes, they are relatively prime.

Yes, they are relatively prime.
Are 144 and 4 relatively prime?
No, they are not relatively prime.
Are 14 and 49 relatively prime?

What is the relatively prime number of 13 and 4?
13 and 4 are relatively prime.
Is 4 and 21 relatively prime?
Yes, they are relatively prime.
Are 4 and 15 relatively prime?
Yes, 4 and 15 are relatively prime.
Are 4 and 21 relatively prime?
Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
Is 7 and 56 relatively prime?
No, 56 is not prime.
What are relatively prime integers?
Two numbers are considered relatively prime if their GCF is 1. 4 and 9 are relatively prime.
