No, they're both divisible by three
No.
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
The numbers that multiply to get 147 are its prime factors. To find the prime factors of 147, we start by dividing it by the smallest prime number, which is 3. 147 ÷ 3 = 49. Then, we divide 49 by 7 (7 is also a prime number), which gives us 7. Therefore, the numbers that multiply to get 147 are 3, 7, and 7.
No. They are both multiples of 3.
3 x 7 x 7 = 147
No because they both have more than two factors
3 x 7 x 7
They are 3 and 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
