HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 865, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 816, 865, 565 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 816, 865, 565 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 816, 865, 565 is 1.

HCF(816, 865, 565) = 1

HCF of 816, 865, 565 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 816, 865, 565 is 1.

Highest Common Factor of 816,865,565 using Euclid's algorithm

Highest Common Factor of 816,865,565 is 1

Step 1: Since 865 > 816, we apply the division lemma to 865 and 816, to get

865 = 816 x 1 + 49

Step 2: Since the reminder 816 ≠ 0, we apply division lemma to 49 and 816, to get

816 = 49 x 16 + 32

Step 3: We consider the new divisor 49 and the new remainder 32, and apply the division lemma to get

49 = 32 x 1 + 17

We consider the new divisor 32 and the new remainder 17,and apply the division lemma to get

32 = 17 x 1 + 15

We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get

17 = 15 x 1 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 816 and 865 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(32,17) = HCF(49,32) = HCF(816,49) = HCF(865,816) .


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

Step 1: Since 565 > 1, we apply the division lemma to 565 and 1, to get

565 = 1 x 565 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 565 is 1

Notice that 1 = HCF(565,1) .
