HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 323, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 323, 438 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 323, 438 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 323, 438 is 1.

HCF(323, 438) = 1

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

HCF of:

Highest common factor (HCF) of 323, 438 is 1.

Highest Common Factor of 323,438 using Euclid's algorithm

Highest Common Factor of 323,438 is 1

Step 1: Since 438 > 323, we apply the division lemma to 438 and 323, to get

438 = 323 x 1 + 115

Step 2: Since the reminder 323 ≠ 0, we apply division lemma to 115 and 323, to get

323 = 115 x 2 + 93

Step 3: We consider the new divisor 115 and the new remainder 93, and apply the division lemma to get

115 = 93 x 1 + 22

We consider the new divisor 93 and the new remainder 22,and apply the division lemma to get

93 = 22 x 4 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 323 and 438 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(93,22) = HCF(115,93) = HCF(323,115) = HCF(438,323) .
