HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 962, 696, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 962, 696, 815 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 962, 696, 815 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 962, 696, 815 is 1.

HCF(962, 696, 815) = 1

Highest Common Factor of 962,696,815 using Euclid's algorithm

Highest Common Factor of 962,696,815 is 1

Step 1: Since 962 > 696, we apply the division lemma to 962 and 696, to get

962 = 696 x 1 + 266

Step 2: Since the reminder 696 ≠ 0, we apply division lemma to 266 and 696, to get

696 = 266 x 2 + 164

Step 3: We consider the new divisor 266 and the new remainder 164, and apply the division lemma to get

266 = 164 x 1 + 102

We consider the new divisor 164 and the new remainder 102,and apply the division lemma to get

164 = 102 x 1 + 62

We consider the new divisor 102 and the new remainder 62,and apply the division lemma to get

102 = 62 x 1 + 40

We consider the new divisor 62 and the new remainder 40,and apply the division lemma to get

62 = 40 x 1 + 22

We consider the new divisor 40 and the new remainder 22,and apply the division lemma to get

40 = 22 x 1 + 18

We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get

22 = 18 x 1 + 4

We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get

18 = 4 x 4 + 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 962 and 696 is 2

Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(40,22) = HCF(62,40) = HCF(102,62) = HCF(164,102) = HCF(266,164) = HCF(696,266) = HCF(962,696) .

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

Step 1: Since 815 > 2, we apply the division lemma to 815 and 2, to get

815 = 2 x 407 + 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 815 is 1

Notice that 1 = HCF(2,1) = HCF(815,2) .
