HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 235, 381, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 235, 381, 53 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 235, 381, 53 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 235, 381, 53 is 1.

HCF(235, 381, 53) = 1

Highest common factor (HCF) of 235, 381, 53 is 1.

Highest Common Factor of 235,381,53 using Euclid's algorithm

Highest Common Factor of 235,381,53 is 1

Step 1: Since 381 > 235, we apply the division lemma to 381 and 235, to get

381 = 235 x 1 + 146

Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 146 and 235, to get

235 = 146 x 1 + 89

Step 3: We consider the new divisor 146 and the new remainder 89, and apply the division lemma to get

146 = 89 x 1 + 57

We consider the new divisor 89 and the new remainder 57,and apply the division lemma to get

89 = 57 x 1 + 32

We consider the new divisor 57 and the new remainder 32,and apply the division lemma to get

57 = 32 x 1 + 25

We consider the new divisor 32 and the new remainder 25,and apply the division lemma to get

32 = 25 x 1 + 7

We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get

25 = 7 x 3 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 235 and 381 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(57,32) = HCF(89,57) = HCF(146,89) = HCF(235,146) = HCF(381,235) .

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

Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get

53 = 1 x 53 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1

Notice that 1 = HCF(53,1) .
