HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 963, 605, 291, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 963, 605, 291, 651 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 963, 605, 291, 651 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 963, 605, 291, 651 is 1.

HCF(963, 605, 291, 651) = 1

Highest common factor (HCF) of 963, 605, 291, 651 is 1.

Highest Common Factor of 963,605,291,651 using Euclid's algorithm

Highest Common Factor of 963,605,291,651 is 1

Step 1: Since 963 > 605, we apply the division lemma to 963 and 605, to get

963 = 605 x 1 + 358

Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 358 and 605, to get

605 = 358 x 1 + 247

Step 3: We consider the new divisor 358 and the new remainder 247, and apply the division lemma to get

358 = 247 x 1 + 111

We consider the new divisor 247 and the new remainder 111,and apply the division lemma to get

247 = 111 x 2 + 25

We consider the new divisor 111 and the new remainder 25,and apply the division lemma to get

111 = 25 x 4 + 11

We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get

25 = 11 x 2 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 963 and 605 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(111,25) = HCF(247,111) = HCF(358,247) = HCF(605,358) = HCF(963,605) .

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

Step 1: Since 291 > 1, we apply the division lemma to 291 and 1, to get

291 = 1 x 291 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 291 is 1

Notice that 1 = HCF(291,1) .

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

Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get

651 = 1 x 651 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1

Notice that 1 = HCF(651,1) .
