HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 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 845, 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 845, 433 is 1.

HCF(845, 433) = 1

Highest common factor (HCF) of 845, 433 is 1.

Highest Common Factor of 845,433 using Euclid's algorithm

Highest Common Factor of 845,433 is 1

Step 1: Since 845 > 433, we apply the division lemma to 845 and 433, to get

845 = 433 x 1 + 412

Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 412 and 433, to get

433 = 412 x 1 + 21

Step 3: We consider the new divisor 412 and the new remainder 21, and apply the division lemma to get

412 = 21 x 19 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 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 845 and 433 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(412,21) = HCF(433,412) = HCF(845,433) .
