HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 495, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 561, 495, 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 561, 495, 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 561, 495, 613 is 1.

HCF(561, 495, 613) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 561, 495, 613 is 1.

Highest Common Factor of 561,495,613 using Euclid's algorithm

Highest Common Factor of 561,495,613 is 1

Step 1: Since 561 > 495, we apply the division lemma to 561 and 495, to get

561 = 495 x 1 + 66

Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 66 and 495, to get

495 = 66 x 7 + 33

Step 3: We consider the new divisor 66 and the new remainder 33, and apply the division lemma to get

66 = 33 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 561 and 495 is 33

Notice that 33 = HCF(66,33) = HCF(495,66) = HCF(561,495) .


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

Step 1: Since 613 > 33, we apply the division lemma to 613 and 33, to get

613 = 33 x 18 + 19

Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 19 and 33, to get

33 = 19 x 1 + 14

Step 3: We consider the new divisor 19 and the new remainder 14, and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 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 33 and 613 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(613,33) .
