HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 904, 19, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 531, 904, 19, 231 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 531, 904, 19, 231 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 531, 904, 19, 231 is 1.

HCF(531, 904, 19, 231) = 1

Highest common factor (HCF) of 531, 904, 19, 231 is 1.

Highest Common Factor of 531,904,19,231 using Euclid's algorithm

Highest Common Factor of 531,904,19,231 is 1

Step 1: Since 904 > 531, we apply the division lemma to 904 and 531, to get

904 = 531 x 1 + 373

Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 373 and 531, to get

531 = 373 x 1 + 158

Step 3: We consider the new divisor 373 and the new remainder 158, and apply the division lemma to get

373 = 158 x 2 + 57

We consider the new divisor 158 and the new remainder 57,and apply the division lemma to get

158 = 57 x 2 + 44

We consider the new divisor 57 and the new remainder 44,and apply the division lemma to get

57 = 44 x 1 + 13

We consider the new divisor 44 and the new remainder 13,and apply the division lemma to get

44 = 13 x 3 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 531 and 904 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(57,44) = HCF(158,57) = HCF(373,158) = HCF(531,373) = HCF(904,531) .

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

Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1

Notice that 1 = HCF(19,1) .

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

Step 1: Since 231 > 1, we apply the division lemma to 231 and 1, to get

231 = 1 x 231 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 231 is 1

Notice that 1 = HCF(231,1) .
