HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 206, 121, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 81, 206, 121, 613 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 81, 206, 121, 613 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 81, 206, 121, 613 is 1.

HCF(81, 206, 121, 613) = 1

Highest Common Factor of 81,206,121,613 using Euclid's algorithm

Highest Common Factor of 81,206,121,613 is 1

Step 1: Since 206 > 81, we apply the division lemma to 206 and 81, to get

206 = 81 x 2 + 44

Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 44 and 81, to get

81 = 44 x 1 + 37

Step 3: We consider the new divisor 44 and the new remainder 37, and apply the division lemma to get

44 = 37 x 1 + 7

We consider the new divisor 37 and the new remainder 7,and apply the division lemma to get

37 = 7 x 5 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 81 and 206 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(37,7) = HCF(44,37) = HCF(81,44) = HCF(206,81) .


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

Step 1: Since 121 > 1, we apply the division lemma to 121 and 1, to get

121 = 1 x 121 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 121 is 1

Notice that 1 = HCF(121,1) .


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

Step 1: Since 613 > 1, we apply the division lemma to 613 and 1, to get

613 = 1 x 613 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 613 is 1

Notice that 1 = HCF(613,1) .
