HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 563, 491, 335, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 563, 491, 335, 74 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 563, 491, 335, 74 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 563, 491, 335, 74 is 1.

HCF(563, 491, 335, 74) = 1

Highest common factor (HCF) of 563, 491, 335, 74 is 1.

Highest Common Factor of 563,491,335,74 using Euclid's algorithm

Highest Common Factor of 563,491,335,74 is 1

Step 1: Since 563 > 491, we apply the division lemma to 563 and 491, to get

563 = 491 x 1 + 72

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 72 and 491, to get

491 = 72 x 6 + 59

Step 3: We consider the new divisor 72 and the new remainder 59, and apply the division lemma to get

72 = 59 x 1 + 13

We consider the new divisor 59 and the new remainder 13,and apply the division lemma to get

59 = 13 x 4 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 563 and 491 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(59,13) = HCF(72,59) = HCF(491,72) = HCF(563,491) .

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

Step 1: Since 335 > 1, we apply the division lemma to 335 and 1, to get

335 = 1 x 335 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 335 is 1

Notice that 1 = HCF(335,1) .

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

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

74 = 1 x 74 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1

Notice that 1 = HCF(74,1) .
