HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 535, 682, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 535, 682, 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 535, 682, 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 535, 682, 720 is 1.

HCF(535, 682, 720) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 535, 682, 720 is 1.

Highest Common Factor of 535,682,720 using Euclid's algorithm

Highest Common Factor of 535,682,720 is 1

Step 1: Since 682 > 535, we apply the division lemma to 682 and 535, to get

682 = 535 x 1 + 147

Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 147 and 535, to get

535 = 147 x 3 + 94

Step 3: We consider the new divisor 147 and the new remainder 94, and apply the division lemma to get

147 = 94 x 1 + 53

We consider the new divisor 94 and the new remainder 53,and apply the division lemma to get

94 = 53 x 1 + 41

We consider the new divisor 53 and the new remainder 41,and apply the division lemma to get

53 = 41 x 1 + 12

We consider the new divisor 41 and the new remainder 12,and apply the division lemma to get

41 = 12 x 3 + 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 535 and 682 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(41,12) = HCF(53,41) = HCF(94,53) = HCF(147,94) = HCF(535,147) = HCF(682,535) .

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) .
