HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 515, 964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 384, 515, 964 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 384, 515, 964 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 384, 515, 964 is 1.

HCF(384, 515, 964) = 1

HCF of 384, 515, 964 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 384, 515, 964 is 1.

Highest Common Factor of 384,515,964 using Euclid's algorithm

Highest Common Factor of 384,515,964 is 1

Step 1: Since 515 > 384, we apply the division lemma to 515 and 384, to get

515 = 384 x 1 + 131

Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 131 and 384, to get

384 = 131 x 2 + 122

Step 3: We consider the new divisor 131 and the new remainder 122, and apply the division lemma to get

131 = 122 x 1 + 9

We consider the new divisor 122 and the new remainder 9,and apply the division lemma to get

122 = 9 x 13 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 384 and 515 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(122,9) = HCF(131,122) = HCF(384,131) = HCF(515,384) .

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

Step 1: Since 964 > 1, we apply the division lemma to 964 and 1, to get

964 = 1 x 964 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 964 is 1

Notice that 1 = HCF(964,1) .
