HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 432, 338 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 805, 432, 338 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 805, 432, 338 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 805, 432, 338 is 1.

HCF(805, 432, 338) = 1

Highest common factor (HCF) of 805, 432, 338 is 1.

Highest Common Factor of 805,432,338 using Euclid's algorithm

Highest Common Factor of 805,432,338 is 1

Step 1: Since 805 > 432, we apply the division lemma to 805 and 432, to get

805 = 432 x 1 + 373

Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 373 and 432, to get

432 = 373 x 1 + 59

Step 3: We consider the new divisor 373 and the new remainder 59, and apply the division lemma to get

373 = 59 x 6 + 19

We consider the new divisor 59 and the new remainder 19,and apply the division lemma to get

59 = 19 x 3 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 805 and 432 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(59,19) = HCF(373,59) = HCF(432,373) = HCF(805,432) .

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

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

338 = 1 x 338 + 0

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

Notice that 1 = HCF(338,1) .
