HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 73, 11, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 43, 73, 11, 694 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 43, 73, 11, 694 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 43, 73, 11, 694 is 1.

HCF(43, 73, 11, 694) = 1

HCF of 43, 73, 11, 694 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 43, 73, 11, 694 is 1.

Highest Common Factor of 43,73,11,694 using Euclid's algorithm

Highest Common Factor of 43,73,11,694 is 1

Step 1: Since 73 > 43, we apply the division lemma to 73 and 43, to get

73 = 43 x 1 + 30

Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 30 and 43, to get

43 = 30 x 1 + 13

Step 3: We consider the new divisor 30 and the new remainder 13, and apply the division lemma to get

30 = 13 x 2 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 73 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(43,30) = HCF(73,43) .


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

Step 1: Since 11 > 1, we apply the division lemma to 11 and 1, to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 11 is 1

Notice that 1 = HCF(11,1) .


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

Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get

694 = 1 x 694 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1

Notice that 1 = HCF(694,1) .
