HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 963, 547 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 221, 963, 547 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 221, 963, 547 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 221, 963, 547 is 1.

HCF(221, 963, 547) = 1

HCF of 221, 963, 547 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 221, 963, 547 is 1.

Highest Common Factor of 221,963,547 using Euclid's algorithm

Highest Common Factor of 221,963,547 is 1

Step 1: Since 963 > 221, we apply the division lemma to 963 and 221, to get

963 = 221 x 4 + 79

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 79 and 221, to get

221 = 79 x 2 + 63

Step 3: We consider the new divisor 79 and the new remainder 63, and apply the division lemma to get

79 = 63 x 1 + 16

We consider the new divisor 63 and the new remainder 16,and apply the division lemma to get

63 = 16 x 3 + 15

We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get

16 = 15 x 1 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 221 and 963 is 1

Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(63,16) = HCF(79,63) = HCF(221,79) = HCF(963,221) .

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

Step 1: Since 547 > 1, we apply the division lemma to 547 and 1, to get

547 = 1 x 547 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 547 is 1

Notice that 1 = HCF(547,1) .
