HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 9556 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 551, 9556 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 551, 9556 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 551, 9556 is 1.

HCF(551, 9556) = 1

HCF of 551, 9556 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 551, 9556 is 1.

Highest Common Factor of 551,9556 using Euclid's algorithm

Highest Common Factor of 551,9556 is 1

Step 1: Since 9556 > 551, we apply the division lemma to 9556 and 551, to get

9556 = 551 x 17 + 189

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 189 and 551, to get

551 = 189 x 2 + 173

Step 3: We consider the new divisor 189 and the new remainder 173, and apply the division lemma to get

189 = 173 x 1 + 16

We consider the new divisor 173 and the new remainder 16,and apply the division lemma to get

173 = 16 x 10 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 551 and 9556 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(173,16) = HCF(189,173) = HCF(551,189) = HCF(9556,551) .
