A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.
One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 39 are 1, 3, 13, and 39.
The factors of 91 are 1, 7, 13, and 91.
The factors of 143 are 1, 11, 13, and 143.
The common factors are 1 and 13. Therefore, the greatest common factor is 13.
The GCF of 39, 143, and 156 is 13. 13 x 3 = 39 13 x 11 = 143 13 x 12 = 156 39 is the product of two prime numbers , 3 and 13. Remember, a prime number is a number divisible only by 1 and itself. So, you can deduce that the factor you are looking for must either be 13 or three. Since you are looking for the greatest common factor, you now have to find out which number is greater ... ... and this is .... 13 !
