HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 843, 755 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 843, 755 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 843, 755 is 1.

HCF(843, 755) = 1

Highest common factor (HCF) of 843, 755 is 1.

Highest Common Factor of 843,755 using Euclid's algorithm

Highest Common Factor of 843,755 is 1

Step 1: Since 843 > 755, we apply the division lemma to 843 and 755, to get

843 = 755 x 1 + 88

Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 88 and 755, to get

755 = 88 x 8 + 51

Step 3: We consider the new divisor 88 and the new remainder 51, and apply the division lemma to get

88 = 51 x 1 + 37

We consider the new divisor 51 and the new remainder 37,and apply the division lemma to get

51 = 37 x 1 + 14

We consider the new divisor 37 and the new remainder 14,and apply the division lemma to get

37 = 14 x 2 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 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 843 and 755 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(37,14) = HCF(51,37) = HCF(88,51) = HCF(755,88) = HCF(843,755) .
