HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 766, 568, 40, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 766, 568, 40, 787 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 766, 568, 40, 787 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 766, 568, 40, 787 is 1.

HCF(766, 568, 40, 787) = 1

Highest common factor (HCF) of 766, 568, 40, 787 is 1.

Highest Common Factor of 766,568,40,787 using Euclid's algorithm

Highest Common Factor of 766,568,40,787 is 1

Step 1: Since 766 > 568, we apply the division lemma to 766 and 568, to get

766 = 568 x 1 + 198

Step 2: Since the reminder 568 ≠ 0, we apply division lemma to 198 and 568, to get

568 = 198 x 2 + 172

Step 3: We consider the new divisor 198 and the new remainder 172, and apply the division lemma to get

198 = 172 x 1 + 26

We consider the new divisor 172 and the new remainder 26,and apply the division lemma to get

172 = 26 x 6 + 16

We consider the new divisor 26 and the new remainder 16,and apply the division lemma to get

26 = 16 x 1 + 10

We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get

16 = 10 x 1 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 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 766 and 568 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(172,26) = HCF(198,172) = HCF(568,198) = HCF(766,568) .

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

Step 1: Since 40 > 2, we apply the division lemma to 40 and 2, to get

40 = 2 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 40 is 2

Notice that 2 = HCF(40,2) .

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

Step 1: Since 787 > 2, we apply the division lemma to 787 and 2, to get

787 = 2 x 393 + 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 787 is 1

Notice that 1 = HCF(2,1) = HCF(787,2) .
