HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 732, 84 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 732, 84 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 397, 732, 84 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 397, 732, 84 is 1.

HCF(397, 732, 84) = 1

Highest common factor (HCF) of 397, 732, 84 is 1.

Highest Common Factor of 397,732,84 using Euclid's algorithm

Highest Common Factor of 397,732,84 is 1

Step 1: Since 732 > 397, we apply the division lemma to 732 and 397, to get

732 = 397 x 1 + 335

Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 335 and 397, to get

397 = 335 x 1 + 62

Step 3: We consider the new divisor 335 and the new remainder 62, and apply the division lemma to get

335 = 62 x 5 + 25

We consider the new divisor 62 and the new remainder 25,and apply the division lemma to get

62 = 25 x 2 + 12

We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get

25 = 12 x 2 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 732 is 1

Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(62,25) = HCF(335,62) = HCF(397,335) = HCF(732,397) .

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

Step 1: Since 84 > 1, we apply the division lemma to 84 and 1, to get

84 = 1 x 84 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 84 is 1

Notice that 1 = HCF(84,1) .
