HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 47, 691, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 47, 691, 431 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 47, 691, 431 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 47, 691, 431 is 1.

HCF(47, 691, 431) = 1

Highest common factor (HCF) of 47, 691, 431 is 1.

Highest Common Factor of 47,691,431 using Euclid's algorithm

Highest Common Factor of 47,691,431 is 1

Step 1: Since 691 > 47, we apply the division lemma to 691 and 47, to get

691 = 47 x 14 + 33

Step 2: Since the reminder 47 ≠ 0, we apply division lemma to 33 and 47, to get

47 = 33 x 1 + 14

Step 3: We consider the new divisor 33 and the new remainder 14, and apply the division lemma to get

33 = 14 x 2 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 47 and 691 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(691,47) .

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

Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get

431 = 1 x 431 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1

Notice that 1 = HCF(431,1) .
