HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 289, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 993, 289, 694 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 993, 289, 694 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 993, 289, 694 is 1.

HCF(993, 289, 694) = 1

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

HCF of:

Highest common factor (HCF) of 993, 289, 694 is 1.

Highest Common Factor of 993,289,694 using Euclid's algorithm

Highest Common Factor of 993,289,694 is 1

Step 1: Since 993 > 289, we apply the division lemma to 993 and 289, to get

993 = 289 x 3 + 126

Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 126 and 289, to get

289 = 126 x 2 + 37

Step 3: We consider the new divisor 126 and the new remainder 37, and apply the division lemma to get

126 = 37 x 3 + 15

We consider the new divisor 37 and the new remainder 15,and apply the division lemma to get

37 = 15 x 2 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 993 and 289 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(37,15) = HCF(126,37) = HCF(289,126) = HCF(993,289) .

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

Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get

694 = 1 x 694 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1

Notice that 1 = HCF(694,1) .
