Answer:
The common factors of 55 and 145 are 1 and 5.
The greatest common factor of 55 and 145 is 5.
Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.
Methods:
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 55 are 1, 5, 11, and 55.
The factors of 145 are 1, 5, 29, and 145.
The common factors are 1 and 5. Therefore, the greatest common factor is 5.
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor.
The prime factors of 55 are 5 and 11.
The prime factors of 145 are 5 and 29.
The prime factors in common are only the number 5, so the greatest common factor is 5. The factors of 5 are 1 and 5, which are the common factors.
