HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 338, 432 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 491, 338, 432 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 491, 338, 432 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 491, 338, 432 is 1.

HCF(491, 338, 432) = 1

Highest common factor (HCF) of 491, 338, 432 is 1.

Highest Common Factor of 491,338,432 using Euclid's algorithm

Highest Common Factor of 491,338,432 is 1

Step 1: Since 491 > 338, we apply the division lemma to 491 and 338, to get

491 = 338 x 1 + 153

Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 153 and 338, to get

338 = 153 x 2 + 32

Step 3: We consider the new divisor 153 and the new remainder 32, and apply the division lemma to get

153 = 32 x 4 + 25

We consider the new divisor 32 and the new remainder 25,and apply the division lemma to get

32 = 25 x 1 + 7

We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get

25 = 7 x 3 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 338 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(153,32) = HCF(338,153) = HCF(491,338) .

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

Step 1: Since 432 > 1, we apply the division lemma to 432 and 1, to get

432 = 1 x 432 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 432 is 1

Notice that 1 = HCF(432,1) .
