HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 862, 197, 838 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 862, 197, 838 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 862, 197, 838 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 862, 197, 838 is 1.

HCF(862, 197, 838) = 1

HCF of 862, 197, 838 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 862, 197, 838 is 1.

Highest Common Factor of 862,197,838 using Euclid's algorithm

Highest Common Factor of 862,197,838 is 1

Step 1: Since 862 > 197, we apply the division lemma to 862 and 197, to get

862 = 197 x 4 + 74

Step 2: Since the reminder 197 ≠ 0, we apply division lemma to 74 and 197, to get

197 = 74 x 2 + 49

Step 3: We consider the new divisor 74 and the new remainder 49, and apply the division lemma to get

74 = 49 x 1 + 25

We consider the new divisor 49 and the new remainder 25,and apply the division lemma to get

49 = 25 x 1 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 862 and 197 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(49,25) = HCF(74,49) = HCF(197,74) = HCF(862,197) .

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

Step 1: Since 838 > 1, we apply the division lemma to 838 and 1, to get

838 = 1 x 838 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 838 is 1

Notice that 1 = HCF(838,1) .
