HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 49, 31, 564 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 49, 31, 564 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 49, 31, 564 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 49, 31, 564 is 1.

HCF(49, 31, 564) = 1

HCF of 49, 31, 564 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 49, 31, 564 is 1.

Highest Common Factor of 49,31,564 using Euclid's algorithm

Highest Common Factor of 49,31,564 is 1

Step 1: Since 49 > 31, we apply the division lemma to 49 and 31, to get

49 = 31 x 1 + 18

Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 18 and 31, to get

31 = 18 x 1 + 13

Step 3: We consider the new divisor 18 and the new remainder 13, and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 49 and 31 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(49,31) .

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

Step 1: Since 564 > 1, we apply the division lemma to 564 and 1, to get

564 = 1 x 564 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 564 is 1

Notice that 1 = HCF(564,1) .
