1 and 13
To find the highest common factor (HCF) of 39, 143, and 169, we need to first find the prime factors of each number. The prime factors of 39 are 3 and 13, the prime factors of 143 are 11 and 13, and the prime factors of 169 are 13 and 13. The HCF is the product of the common prime factors raised to the lowest power they appear, which in this case is 13. Therefore, the HCF of 39, 143, and 169 is 13.
33, 39, 143, 169, 429, 507, 1859, 5577
It is: 13
It is: 13
The GCF of 143 and 169 is 13. 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 143 are 1, 11, 13, and 143. The factors of 169 are 1, 13, and 169. The common factors are 1 and 13. Therefore, the greatest common factor is 13.
