HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 74, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 63, 74, 13 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 63, 74, 13 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 63, 74, 13 is 1.

HCF(63, 74, 13) = 1

HCF of 63, 74, 13 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 63, 74, 13 is 1.

Highest Common Factor of 63,74,13 using Euclid's algorithm

Highest Common Factor of 63,74,13 is 1

Step 1: Since 74 > 63, we apply the division lemma to 74 and 63, to get

74 = 63 x 1 + 11

Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 11 and 63, to get

63 = 11 x 5 + 8

Step 3: We consider the new divisor 11 and the new remainder 8, and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 63 and 74 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(63,11) = HCF(74,63) .

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

Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1

Notice that 1 = HCF(13,1) .
