HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 955, 565 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 865, 955, 565 is 5 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 865, 955, 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 865, 955, 565 is 5.

HCF(865, 955, 565) = 5

HCF of 865, 955, 565 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 865, 955, 565 is 5.

Highest Common Factor of 865,955,565 using Euclid's algorithm

Highest Common Factor of 865,955,565 is 5

Step 1: Since 955 > 865, we apply the division lemma to 955 and 865, to get

955 = 865 x 1 + 90

Step 2: Since the reminder 865 ≠ 0, we apply division lemma to 90 and 865, to get

865 = 90 x 9 + 55

Step 3: We consider the new divisor 90 and the new remainder 55, and apply the division lemma to get

90 = 55 x 1 + 35

We consider the new divisor 55 and the new remainder 35,and apply the division lemma to get

55 = 35 x 1 + 20

We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get

35 = 20 x 1 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 865 and 955 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(55,35) = HCF(90,55) = HCF(865,90) = HCF(955,865) .

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

Step 1: Since 565 > 5, we apply the division lemma to 565 and 5, to get

565 = 5 x 113 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 565 is 5

Notice that 5 = HCF(565,5) .
