HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 444, 797, 636 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 444, 797, 636 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 444, 797, 636 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 444, 797, 636 is 1.

HCF(444, 797, 636) = 1

Highest common factor (HCF) of 444, 797, 636 is 1.

Highest Common Factor of 444,797,636 using Euclid's algorithm

Highest Common Factor of 444,797,636 is 1

Step 1: Since 797 > 444, we apply the division lemma to 797 and 444, to get

797 = 444 x 1 + 353

Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 353 and 444, to get

444 = 353 x 1 + 91

Step 3: We consider the new divisor 353 and the new remainder 91, and apply the division lemma to get

353 = 91 x 3 + 80

We consider the new divisor 91 and the new remainder 80,and apply the division lemma to get

91 = 80 x 1 + 11

We consider the new divisor 80 and the new remainder 11,and apply the division lemma to get

80 = 11 x 7 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 444 and 797 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(80,11) = HCF(91,80) = HCF(353,91) = HCF(444,353) = HCF(797,444) .

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

Step 1: Since 636 > 1, we apply the division lemma to 636 and 1, to get

636 = 1 x 636 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 636 is 1

Notice that 1 = HCF(636,1) .
