HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 422, 788, 513 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 422, 788, 513 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 422, 788, 513 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 422, 788, 513 is 1.

HCF(422, 788, 513) = 1

Highest common factor (HCF) of 422, 788, 513 is 1.

Highest Common Factor of 422,788,513 using Euclid's algorithm

Highest Common Factor of 422,788,513 is 1

Step 1: Since 788 > 422, we apply the division lemma to 788 and 422, to get

788 = 422 x 1 + 366

Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 366 and 422, to get

422 = 366 x 1 + 56

Step 3: We consider the new divisor 366 and the new remainder 56, and apply the division lemma to get

366 = 56 x 6 + 30

We consider the new divisor 56 and the new remainder 30,and apply the division lemma to get

56 = 30 x 1 + 26

We consider the new divisor 30 and the new remainder 26,and apply the division lemma to get

30 = 26 x 1 + 4

We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get

26 = 4 x 6 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 422 and 788 is 2

Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(56,30) = HCF(366,56) = HCF(422,366) = HCF(788,422) .

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

Step 1: Since 513 > 2, we apply the division lemma to 513 and 2, to get

513 = 2 x 256 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 513 is 1

Notice that 1 = HCF(2,1) = HCF(513,2) .
