HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 512, 361, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 512, 361, 57 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 512, 361, 57 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 512, 361, 57 is 1.

HCF(512, 361, 57) = 1

HCF of 512, 361, 57 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 512, 361, 57 is 1.

Highest Common Factor of 512,361,57 using Euclid's algorithm

Highest Common Factor of 512,361,57 is 1

Step 1: Since 512 > 361, we apply the division lemma to 512 and 361, to get

512 = 361 x 1 + 151

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 151 and 361, to get

361 = 151 x 2 + 59

Step 3: We consider the new divisor 151 and the new remainder 59, and apply the division lemma to get

151 = 59 x 2 + 33

We consider the new divisor 59 and the new remainder 33,and apply the division lemma to get

59 = 33 x 1 + 26

We consider the new divisor 33 and the new remainder 26,and apply the division lemma to get

33 = 26 x 1 + 7

We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get

26 = 7 x 3 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 512 and 361 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(33,26) = HCF(59,33) = HCF(151,59) = HCF(361,151) = HCF(512,361) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
