HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 363, 643, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 363, 643, 433 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 363, 643, 433 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 363, 643, 433 is 1.

HCF(363, 643, 433) = 1

Highest common factor (HCF) of 363, 643, 433 is 1.

Highest Common Factor of 363,643,433 using Euclid's algorithm

Highest Common Factor of 363,643,433 is 1

Step 1: Since 643 > 363, we apply the division lemma to 643 and 363, to get

643 = 363 x 1 + 280

Step 2: Since the reminder 363 ≠ 0, we apply division lemma to 280 and 363, to get

363 = 280 x 1 + 83

Step 3: We consider the new divisor 280 and the new remainder 83, and apply the division lemma to get

280 = 83 x 3 + 31

We consider the new divisor 83 and the new remainder 31,and apply the division lemma to get

83 = 31 x 2 + 21

We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get

31 = 21 x 1 + 10

We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get

21 = 10 x 2 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 363 and 643 is 1

Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(83,31) = HCF(280,83) = HCF(363,280) = HCF(643,363) .

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

Step 1: Since 433 > 1, we apply the division lemma to 433 and 1, to get

433 = 1 x 433 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 433 is 1

Notice that 1 = HCF(433,1) .
