There are two prime factors of 45, they are 3 and 5. The prime factors of 54 are 2 and 3.
It is: 5
The greatest common factor of 45 and 320 is 5.
The GCF is 15 The greatest prime factor in common is 5..
It is: 3*3*5 = 45
The GCF of 45 and 80 is 5. Prime factors: 45 = 5x3x3 80 = 5x2x2x2x2 the only prime factor in both is 5, and so the highest common factor is 5. Alternative method: 80 mod 45 = 35 45 mod 35 = 10 35 mod 10 = 5 10 mod 5 = 0 so HCF = 5.
15 is a factor of 45, but it is not a prime number.
6 is not a factor of 80. 6 is not a prime number.
5, yes. 45, no.
39 and 45 are not relatively prime because they have 3 as a common factor. Relatively prime numbers have no common factor greater than 1.
Yes
Use a factor tree. 45 15,3 5,3,3
That's prime factorization. 45 15,3 5,3,3
45 and 36 are not relatively prime because they have 3 as a common factor.
