HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 639, 594 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 991, 639, 594 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 991, 639, 594 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 991, 639, 594 is 1.

HCF(991, 639, 594) = 1

HCF of 991, 639, 594 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 991, 639, 594 is 1.

Highest Common Factor of 991,639,594 using Euclid's algorithm

Highest Common Factor of 991,639,594 is 1

Step 1: Since 991 > 639, we apply the division lemma to 991 and 639, to get

991 = 639 x 1 + 352

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 352 and 639, to get

639 = 352 x 1 + 287

Step 3: We consider the new divisor 352 and the new remainder 287, and apply the division lemma to get

352 = 287 x 1 + 65

We consider the new divisor 287 and the new remainder 65,and apply the division lemma to get

287 = 65 x 4 + 27

We consider the new divisor 65 and the new remainder 27,and apply the division lemma to get

65 = 27 x 2 + 11

We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get

27 = 11 x 2 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 639 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(65,27) = HCF(287,65) = HCF(352,287) = HCF(639,352) = HCF(991,639) .

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

Step 1: Since 594 > 1, we apply the division lemma to 594 and 1, to get

594 = 1 x 594 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 594 is 1

Notice that 1 = HCF(594,1) .
