HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 367, 691, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 367, 691, 523 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 367, 691, 523 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 367, 691, 523 is 1.

HCF(367, 691, 523) = 1

Highest common factor (HCF) of 367, 691, 523 is 1.

Highest Common Factor of 367,691,523 using Euclid's algorithm

Highest Common Factor of 367,691,523 is 1

Step 1: Since 691 > 367, we apply the division lemma to 691 and 367, to get

691 = 367 x 1 + 324

Step 2: Since the reminder 367 ≠ 0, we apply division lemma to 324 and 367, to get

367 = 324 x 1 + 43

Step 3: We consider the new divisor 324 and the new remainder 43, and apply the division lemma to get

324 = 43 x 7 + 23

We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get

43 = 23 x 1 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 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 367 and 691 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(324,43) = HCF(367,324) = HCF(691,367) .

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

Step 1: Since 523 > 1, we apply the division lemma to 523 and 1, to get

523 = 1 x 523 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 523 is 1

Notice that 1 = HCF(523,1) .
