HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 766, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 402, 766, 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 402, 766, 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 402, 766, 651 is 1.

HCF(402, 766, 651) = 1

Highest common factor (HCF) of 402, 766, 651 is 1.

Highest Common Factor of 402,766,651 using Euclid's algorithm

Highest Common Factor of 402,766,651 is 1

Step 1: Since 766 > 402, we apply the division lemma to 766 and 402, to get

766 = 402 x 1 + 364

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 364 and 402, to get

402 = 364 x 1 + 38

Step 3: We consider the new divisor 364 and the new remainder 38, and apply the division lemma to get

364 = 38 x 9 + 22

We consider the new divisor 38 and the new remainder 22,and apply the division lemma to get

38 = 22 x 1 + 16

We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get

22 = 16 x 1 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 402 and 766 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(38,22) = HCF(364,38) = HCF(402,364) = HCF(766,402) .

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

Step 1: Since 651 > 2, we apply the division lemma to 651 and 2, to get

651 = 2 x 325 + 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 651 is 1

Notice that 1 = HCF(2,1) = HCF(651,2) .
