HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 755 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 869, 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 869, 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 869, 755 is 1.

HCF(869, 755) = 1

Highest common factor (HCF) of 869, 755 is 1.

Highest Common Factor of 869,755 using Euclid's algorithm

Highest Common Factor of 869,755 is 1

Step 1: Since 869 > 755, we apply the division lemma to 869 and 755, to get

869 = 755 x 1 + 114

Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 114 and 755, to get

755 = 114 x 6 + 71

Step 3: We consider the new divisor 114 and the new remainder 71, and apply the division lemma to get

114 = 71 x 1 + 43

We consider the new divisor 71 and the new remainder 43,and apply the division lemma to get

71 = 43 x 1 + 28

We consider the new divisor 43 and the new remainder 28,and apply the division lemma to get

43 = 28 x 1 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 869 and 755 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(43,28) = HCF(71,43) = HCF(114,71) = HCF(755,114) = HCF(869,755) .
