HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 631, 392, 324 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 631, 392, 324 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 631, 392, 324 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 631, 392, 324 is 1.

HCF(631, 392, 324) = 1

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

HCF of:

Highest common factor (HCF) of 631, 392, 324 is 1.

Highest Common Factor of 631,392,324 using Euclid's algorithm

Highest Common Factor of 631,392,324 is 1

Step 1: Since 631 > 392, we apply the division lemma to 631 and 392, to get

631 = 392 x 1 + 239

Step 2: Since the reminder 392 ≠ 0, we apply division lemma to 239 and 392, to get

392 = 239 x 1 + 153

Step 3: We consider the new divisor 239 and the new remainder 153, and apply the division lemma to get

239 = 153 x 1 + 86

We consider the new divisor 153 and the new remainder 86,and apply the division lemma to get

153 = 86 x 1 + 67

We consider the new divisor 86 and the new remainder 67,and apply the division lemma to get

86 = 67 x 1 + 19

We consider the new divisor 67 and the new remainder 19,and apply the division lemma to get

67 = 19 x 3 + 10

We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get

19 = 10 x 1 + 9

We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 631 and 392 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(67,19) = HCF(86,67) = HCF(153,86) = HCF(239,153) = HCF(392,239) = HCF(631,392) .

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

Step 1: Since 324 > 1, we apply the division lemma to 324 and 1, to get

324 = 1 x 324 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 324 is 1

Notice that 1 = HCF(324,1) .
