The greatest common factor (usually abbreviated GCF) of 15, 35, and 20, is 5.
5
The GCF is 25.
It is: 3 to 7 by dividing both by their HCF which is 5
The GCF is 35.
The GCF is 7.
5=5x1 35=5x7 HCF=5
The common factors of 15 and 75 are: 1, 3, 5, and 15 of which 15 is the HCF of 15 and 75
The HCF is 7.
The GCF is 1.
It is: 35
The HCF is 7.
The Highest Common Factor (HCF) of 35 and 80 is the largest number that divides both 35 and 80 without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then dividing the divisor by the remainder until the remainder is zero. The HCF of 35 and 80 is 5.
