HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 898, 563, 991 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 898, 563, 991 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 898, 563, 991 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 898, 563, 991 is 1.

HCF(898, 563, 991) = 1

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

HCF of:

Highest common factor (HCF) of 898, 563, 991 is 1.

Highest Common Factor of 898,563,991 using Euclid's algorithm

Highest Common Factor of 898,563,991 is 1

Step 1: Since 898 > 563, we apply the division lemma to 898 and 563, to get

898 = 563 x 1 + 335

Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 335 and 563, to get

563 = 335 x 1 + 228

Step 3: We consider the new divisor 335 and the new remainder 228, and apply the division lemma to get

335 = 228 x 1 + 107

We consider the new divisor 228 and the new remainder 107,and apply the division lemma to get

228 = 107 x 2 + 14

We consider the new divisor 107 and the new remainder 14,and apply the division lemma to get

107 = 14 x 7 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 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 898 and 563 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(107,14) = HCF(228,107) = HCF(335,228) = HCF(563,335) = HCF(898,563) .

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

Step 1: Since 991 > 1, we apply the division lemma to 991 and 1, to get

991 = 1 x 991 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 991 is 1

Notice that 1 = HCF(991,1) .
