HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 169, 47 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 169, 47 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 351, 169, 47 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 351, 169, 47 is 1.

HCF(351, 169, 47) = 1

Highest Common Factor of 351,169,47 using Euclid's algorithm

Highest Common Factor of 351,169,47 is 1

Step 1: Since 351 > 169, we apply the division lemma to 351 and 169, to get

351 = 169 x 2 + 13

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 13 and 169, to get

169 = 13 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 351 and 169 is 13

Notice that 13 = HCF(169,13) = HCF(351,169) .

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

Step 1: Since 47 > 13, we apply the division lemma to 47 and 13, to get

47 = 13 x 3 + 8

Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get

13 = 8 x 1 + 5

Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 13 and 47 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(47,13) .
