HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 383, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 383, 543 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 383, 543 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 383, 543 is 1.

HCF(383, 543) = 1

Highest common factor (HCF) of 383, 543 is 1.

Highest Common Factor of 383,543 using Euclid's algorithm

Highest Common Factor of 383,543 is 1

Step 1: Since 543 > 383, we apply the division lemma to 543 and 383, to get

543 = 383 x 1 + 160

Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 160 and 383, to get

383 = 160 x 2 + 63

Step 3: We consider the new divisor 160 and the new remainder 63, and apply the division lemma to get

160 = 63 x 2 + 34

We consider the new divisor 63 and the new remainder 34,and apply the division lemma to get

63 = 34 x 1 + 29

We consider the new divisor 34 and the new remainder 29,and apply the division lemma to get

34 = 29 x 1 + 5

We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get

29 = 5 x 5 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 383 and 543 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(34,29) = HCF(63,34) = HCF(160,63) = HCF(383,160) = HCF(543,383) .
