To find the greatest common factor (GCF) of 84, 105, and 147, you need to identify the common factors of these numbers. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105. The factors of 147 are 1, 3, 7, 21, 49, and 147. The greatest common factor among these three numbers is 21.
The greatest GCF factor is 21! And it is common to the two number as well!
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.
