HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 736, 643, 398 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 736, 643, 398 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 736, 643, 398 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 736, 643, 398 is 1.

HCF(736, 643, 398) = 1

Highest common factor (HCF) of 736, 643, 398 is 1.

Highest Common Factor of 736,643,398 using Euclid's algorithm

Highest Common Factor of 736,643,398 is 1

Step 1: Since 736 > 643, we apply the division lemma to 736 and 643, to get

736 = 643 x 1 + 93

Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 93 and 643, to get

643 = 93 x 6 + 85

Step 3: We consider the new divisor 93 and the new remainder 85, and apply the division lemma to get

93 = 85 x 1 + 8

We consider the new divisor 85 and the new remainder 8,and apply the division lemma to get

85 = 8 x 10 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 736 and 643 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(85,8) = HCF(93,85) = HCF(643,93) = HCF(736,643) .

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

Step 1: Since 398 > 1, we apply the division lemma to 398 and 1, to get

398 = 1 x 398 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 398 is 1

Notice that 1 = HCF(398,1) .
