HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 165, 536 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 177, 165, 536 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 177, 165, 536 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 177, 165, 536 is 1.

HCF(177, 165, 536) = 1

HCF of 177, 165, 536 using Euclid's algorithm

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

Highest common factor (HCF) of 177, 165, 536 is 1.

Highest Common Factor of 177,165,536 using Euclid's algorithm

Highest Common Factor of 177,165,536 is 1

Step 1: Since 177 > 165, we apply the division lemma to 177 and 165, to get

177 = 165 x 1 + 12

Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 12 and 165, to get

165 = 12 x 13 + 9

Step 3: We consider the new divisor 12 and the new remainder 9, and apply the division lemma to get

12 = 9 x 1 + 3

We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 177 and 165 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(165,12) = HCF(177,165) .

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

Step 1: Since 536 > 3, we apply the division lemma to 536 and 3, to get

536 = 3 x 178 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 536 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(536,3) .
