There cannot be any such thing as a "highest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a highest multiple.
The prime factors are: 39 = 3 * 13 143 = 11 * 13 156 = 2 * 2 * 3 * 13 So the greatest common factor is 13.
Factors of 52: 1, 2, 4, 13, 26, 52 Factors of 143: 1, 11, 13, 143 Factors of 156: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 GCF (52, 143, 156) = 13
It is: 13
It is: 13
The GCF is 1.
The GCF 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 !
The prime factors are: 39 = 3 * 13 143 = 11 * 13 156 = 2 * 2 * 3 * 13 So the greatest common factor is 13.
