HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 415, 767, 387 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 415, 767, 387 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 415, 767, 387 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 415, 767, 387 is 1.

HCF(415, 767, 387) = 1

HCF of 415, 767, 387 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 415, 767, 387 is 1.

Highest Common Factor of 415,767,387 using Euclid's algorithm

Highest Common Factor of 415,767,387 is 1

Step 1: Since 767 > 415, we apply the division lemma to 767 and 415, to get

767 = 415 x 1 + 352

Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 352 and 415, to get

415 = 352 x 1 + 63

Step 3: We consider the new divisor 352 and the new remainder 63, and apply the division lemma to get

352 = 63 x 5 + 37

We consider the new divisor 63 and the new remainder 37,and apply the division lemma to get

63 = 37 x 1 + 26

We consider the new divisor 37 and the new remainder 26,and apply the division lemma to get

37 = 26 x 1 + 11

We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get

26 = 11 x 2 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 415 and 767 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(37,26) = HCF(63,37) = HCF(352,63) = HCF(415,352) = HCF(767,415) .

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

Step 1: Since 387 > 1, we apply the division lemma to 387 and 1, to get

387 = 1 x 387 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 387 is 1

Notice that 1 = HCF(387,1) .
