HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 550, 167, 173, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 550, 167, 173, 51 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 550, 167, 173, 51 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 550, 167, 173, 51 is 1.

HCF(550, 167, 173, 51) = 1

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

HCF of:

Highest common factor (HCF) of 550, 167, 173, 51 is 1.

Highest Common Factor of 550,167,173,51 using Euclid's algorithm

Highest Common Factor of 550,167,173,51 is 1

Step 1: Since 550 > 167, we apply the division lemma to 550 and 167, to get

550 = 167 x 3 + 49

Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 49 and 167, to get

167 = 49 x 3 + 20

Step 3: We consider the new divisor 49 and the new remainder 20, and apply the division lemma to get

49 = 20 x 2 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 550 and 167 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(49,20) = HCF(167,49) = HCF(550,167) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get

173 = 1 x 173 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1

Notice that 1 = HCF(173,1) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 51 > 1, we apply the division lemma to 51 and 1, to get

51 = 1 x 51 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 51 is 1

Notice that 1 = HCF(51,1) .
