HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 235, 73, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 235, 73, 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 681, 235, 73, 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 681, 235, 73, 523 is 1.

HCF(681, 235, 73, 523) = 1

Highest Common Factor of 681,235,73,523 using Euclid's algorithm

Highest Common Factor of 681,235,73,523 is 1

Step 1: Since 681 > 235, we apply the division lemma to 681 and 235, to get

681 = 235 x 2 + 211

Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 211 and 235, to get

235 = 211 x 1 + 24

Step 3: We consider the new divisor 211 and the new remainder 24, and apply the division lemma to get

211 = 24 x 8 + 19

We consider the new divisor 24 and the new remainder 19,and apply the division lemma to get

24 = 19 x 1 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 681 and 235 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(211,24) = HCF(235,211) = HCF(681,235) .

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

Step 1: Since 73 > 1, we apply the division lemma to 73 and 1, to get

73 = 1 x 73 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73 is 1

Notice that 1 = HCF(73,1) .

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) .
