HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 706, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 838, 706, 663 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 838, 706, 663 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 838, 706, 663 is 1.

HCF(838, 706, 663) = 1

Highest common factor (HCF) of 838, 706, 663 is 1.

Highest Common Factor of 838,706,663 using Euclid's algorithm

Highest Common Factor of 838,706,663 is 1

Step 1: Since 838 > 706, we apply the division lemma to 838 and 706, to get

838 = 706 x 1 + 132

Step 2: Since the reminder 706 ≠ 0, we apply division lemma to 132 and 706, to get

706 = 132 x 5 + 46

Step 3: We consider the new divisor 132 and the new remainder 46, and apply the division lemma to get

132 = 46 x 2 + 40

We consider the new divisor 46 and the new remainder 40,and apply the division lemma to get

46 = 40 x 1 + 6

We consider the new divisor 40 and the new remainder 6,and apply the division lemma to get

40 = 6 x 6 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 706 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(40,6) = HCF(46,40) = HCF(132,46) = HCF(706,132) = HCF(838,706) .

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

Step 1: Since 663 > 2, we apply the division lemma to 663 and 2, to get

663 = 2 x 331 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 663 is 1

Notice that 1 = HCF(2,1) = HCF(663,2) .
