No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime
They are 3 and 7
No, it is not a prime. 147=3*7*7.
1,3,7,21,49,147 1, & 147 is not the only factors of 147 because 147 is not prime
No, as 21 x 7 = 147
No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime
75,112
No. They are both multiples of 3.
No, they're both divisible by three
75 and 112
3 x 7 x 7 = 147
They are 3 and 7
No because they both have more than two factors
3 x 7 x 7
No, it is not a prime. 147=3*7*7.
To find the greatest common factor of two numbers, you first need to break those numbers down into their prime factors. For 105 and 147 this is: 105 = 3x5x7 147 = 3x7x7 The next step is to identify any common prime factors. In this case, both numbers have a 3 as a prime factor, and a 7 as a prime factor. Multiply these together to get the GCF: 3x7 = 21 Thus the greatest common factor of 105 and 147 is 21.
147=3x7x7
