HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 779, 816 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 630, 779, 816 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 630, 779, 816 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 630, 779, 816 is 1.

HCF(630, 779, 816) = 1

HCF of 630, 779, 816 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 630, 779, 816 is 1.

Highest Common Factor of 630,779,816 using Euclid's algorithm

Highest Common Factor of 630,779,816 is 1

Step 1: Since 779 > 630, we apply the division lemma to 779 and 630, to get

779 = 630 x 1 + 149

Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 149 and 630, to get

630 = 149 x 4 + 34

Step 3: We consider the new divisor 149 and the new remainder 34, and apply the division lemma to get

149 = 34 x 4 + 13

We consider the new divisor 34 and the new remainder 13,and apply the division lemma to get

34 = 13 x 2 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

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 630 and 779 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(34,13) = HCF(149,34) = HCF(630,149) = HCF(779,630) .

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

Step 1: Since 816 > 1, we apply the division lemma to 816 and 1, to get

816 = 1 x 816 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 816 is 1

Notice that 1 = HCF(816,1) .
