5
55... 5 x 55 = 275
55 and 145's highest common factor is five.
It is: 11
The GCF is 55.
55 and 15's highest common factor is five.
There is only one highest common factor which is: hcf(55, 145) = 5 The factors of 55 are: {1, 5, 11, 55} The factors of 145 are: {1, 5, 29, 145} The common factors are: {1, 5} The highest common factor is 5.
The Highest Common Factor (HCF) of 20 and 55 is the largest positive integer that divides both 20 and 55 without leaving a remainder. To find the HCF, we need to determine the common factors of 20 and 55, which are 1 and 5. The highest common factor among these common factors is 5. Therefore, the HCF of 20 and 55 is 5.
The greatest common factor of 18 and 55 is 1.
The GCF is 1.
