HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 9673, 9816 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 436, 9673, 9816 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 436, 9673, 9816 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 436, 9673, 9816 is 1.

HCF(436, 9673, 9816) = 1

HCF of 436, 9673, 9816 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 436, 9673, 9816 is 1.

Highest Common Factor of 436,9673,9816 using Euclid's algorithm

Highest Common Factor of 436,9673,9816 is 1

Step 1: Since 9673 > 436, we apply the division lemma to 9673 and 436, to get

9673 = 436 x 22 + 81

Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 81 and 436, to get

436 = 81 x 5 + 31

Step 3: We consider the new divisor 81 and the new remainder 31, and apply the division lemma to get

81 = 31 x 2 + 19

We consider the new divisor 31 and the new remainder 19,and apply the division lemma to get

31 = 19 x 1 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 436 and 9673 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(31,19) = HCF(81,31) = HCF(436,81) = HCF(9673,436) .

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

Step 1: Since 9816 > 1, we apply the division lemma to 9816 and 1, to get

9816 = 1 x 9816 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9816 is 1

Notice that 1 = HCF(9816,1) .
