HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 802, 965 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 997, 802, 965 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 997, 802, 965 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 997, 802, 965 is 1.

HCF(997, 802, 965) = 1

Highest common factor (HCF) of 997, 802, 965 is 1.

Highest Common Factor of 997,802,965 using Euclid's algorithm

Highest Common Factor of 997,802,965 is 1

Step 1: Since 997 > 802, we apply the division lemma to 997 and 802, to get

997 = 802 x 1 + 195

Step 2: Since the reminder 802 ≠ 0, we apply division lemma to 195 and 802, to get

802 = 195 x 4 + 22

Step 3: We consider the new divisor 195 and the new remainder 22, and apply the division lemma to get

195 = 22 x 8 + 19

We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get

22 = 19 x 1 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 802 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(195,22) = HCF(802,195) = HCF(997,802) .


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

Step 1: Since 965 > 1, we apply the division lemma to 965 and 1, to get

965 = 1 x 965 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 965 is 1

Notice that 1 = HCF(965,1) .
