The least common factor is: 1
7
The GCF is 1.
The GCF is 1.
The greatest common factor for 7 and 28 = 7.
Since 7 is a factor of 35, it is automatically the GCF.
The GCF is 7.
The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9 So the greatest common factor is 1
The least common factor of any set of integers is 1.
140, 280, 420, 560, 700
To find the greatest common factor of any number of given numbers do the following 1) find the prime factors of each number 2) The greatest common factor will be the multiplication of all the common factors in all the given numbers. e.g 3, 7, 10 1) 3=3x1, 7=7x1, 10 = 2x5x1 2) The Greatest common factor here is only 1 e.g. 10,15, 20 1) 10 = 2x5x1, 15= 3x5x1, 20=4x5x1 2) The greatest common factor here is 1x5 = 5
The highest common factor is: 20
