HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 717, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 320, 717, 720 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 320, 717, 720 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 320, 717, 720 is 1.

HCF(320, 717, 720) = 1

Highest Common Factor of 320,717,720 using Euclid's algorithm

Highest Common Factor of 320,717,720 is 1

Step 1: Since 717 > 320, we apply the division lemma to 717 and 320, to get

717 = 320 x 2 + 77

Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 77 and 320, to get

320 = 77 x 4 + 12

Step 3: We consider the new divisor 77 and the new remainder 12, and apply the division lemma to get

77 = 12 x 6 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 320 and 717 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(320,77) = HCF(717,320) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get

720 = 1 x 720 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1

Notice that 1 = HCF(720,1) .
