HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 176, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 209, 176, 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 209, 176, 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 209, 176, 438 is 1.

HCF(209, 176, 438) = 1

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

HCF of:

Highest common factor (HCF) of 209, 176, 438 is 1.

Highest Common Factor of 209,176,438 using Euclid's algorithm

Highest Common Factor of 209,176,438 is 1

Step 1: Since 209 > 176, we apply the division lemma to 209 and 176, to get

209 = 176 x 1 + 33

Step 2: Since the reminder 176 ≠ 0, we apply division lemma to 33 and 176, to get

176 = 33 x 5 + 11

Step 3: We consider the new divisor 33 and the new remainder 11, and apply the division lemma to get

33 = 11 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 209 and 176 is 11

Notice that 11 = HCF(33,11) = HCF(176,33) = HCF(209,176) .

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

Step 1: Since 438 > 11, we apply the division lemma to 438 and 11, to get

438 = 11 x 39 + 9

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 9 and 11, to get

11 = 9 x 1 + 2

Step 3: We consider the new divisor 9 and the new remainder 2, and apply the division lemma to get

9 = 2 x 4 + 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 11 and 438 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(438,11) .
