HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 549, 869 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 549, 869 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 549, 869 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 549, 869 is 1.

HCF(549, 869) = 1

Highest common factor (HCF) of 549, 869 is 1.

Highest Common Factor of 549,869 using Euclid's algorithm

Highest Common Factor of 549,869 is 1

Step 1: Since 869 > 549, we apply the division lemma to 869 and 549, to get

869 = 549 x 1 + 320

Step 2: Since the reminder 549 ≠ 0, we apply division lemma to 320 and 549, to get

549 = 320 x 1 + 229

Step 3: We consider the new divisor 320 and the new remainder 229, and apply the division lemma to get

320 = 229 x 1 + 91

We consider the new divisor 229 and the new remainder 91,and apply the division lemma to get

229 = 91 x 2 + 47

We consider the new divisor 91 and the new remainder 47,and apply the division lemma to get

91 = 47 x 1 + 44

We consider the new divisor 47 and the new remainder 44,and apply the division lemma to get

47 = 44 x 1 + 3

We consider the new divisor 44 and the new remainder 3,and apply the division lemma to get

44 = 3 x 14 + 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 549 and 869 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(44,3) = HCF(47,44) = HCF(91,47) = HCF(229,91) = HCF(320,229) = HCF(549,320) = HCF(869,549) .
