HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 353, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 353, 167 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 555, 353, 167 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 555, 353, 167 is 1.

HCF(555, 353, 167) = 1

Highest common factor (HCF) of 555, 353, 167 is 1.

Highest Common Factor of 555,353,167 using Euclid's algorithm

Highest Common Factor of 555,353,167 is 1

Step 1: Since 555 > 353, we apply the division lemma to 555 and 353, to get

555 = 353 x 1 + 202

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 202 and 353, to get

353 = 202 x 1 + 151

Step 3: We consider the new divisor 202 and the new remainder 151, and apply the division lemma to get

202 = 151 x 1 + 51

We consider the new divisor 151 and the new remainder 51,and apply the division lemma to get

151 = 51 x 2 + 49

We consider the new divisor 51 and the new remainder 49,and apply the division lemma to get

51 = 49 x 1 + 2

We consider the new divisor 49 and the new remainder 2,and apply the division lemma to get

49 = 2 x 24 + 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 555 and 353 is 1

Notice that 1 = HCF(2,1) = HCF(49,2) = HCF(51,49) = HCF(151,51) = HCF(202,151) = HCF(353,202) = HCF(555,353) .

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

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

167 = 1 x 167 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1

Notice that 1 = HCF(167,1) .
