HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 361, 214 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 438, 361, 214 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 438, 361, 214 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 438, 361, 214 is 1.

HCF(438, 361, 214) = 1

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

HCF of:

Highest common factor (HCF) of 438, 361, 214 is 1.

Highest Common Factor of 438,361,214 using Euclid's algorithm

Highest Common Factor of 438,361,214 is 1

Step 1: Since 438 > 361, we apply the division lemma to 438 and 361, to get

438 = 361 x 1 + 77

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 77 and 361, to get

361 = 77 x 4 + 53

Step 3: We consider the new divisor 77 and the new remainder 53, and apply the division lemma to get

77 = 53 x 1 + 24

We consider the new divisor 53 and the new remainder 24,and apply the division lemma to get

53 = 24 x 2 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 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 438 and 361 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(53,24) = HCF(77,53) = HCF(361,77) = HCF(438,361) .

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

Step 1: Since 214 > 1, we apply the division lemma to 214 and 1, to get

214 = 1 x 214 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 214 is 1

Notice that 1 = HCF(214,1) .
