HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 663, 85, 445 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 993, 663, 85, 445 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, 663, 85, 445 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, 663, 85, 445 is 1.

HCF(993, 663, 85, 445) = 1

HCF of 993, 663, 85, 445 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 993, 663, 85, 445 is 1.

Highest Common Factor of 993,663,85,445 using Euclid's algorithm

Highest Common Factor of 993,663,85,445 is 1

Step 1: Since 993 > 663, we apply the division lemma to 993 and 663, to get

993 = 663 x 1 + 330

Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 330 and 663, to get

663 = 330 x 2 + 3

Step 3: We consider the new divisor 330 and the new remainder 3, and apply the division lemma to get

330 = 3 x 110 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 993 and 663 is 3

Notice that 3 = HCF(330,3) = HCF(663,330) = HCF(993,663) .


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

Step 1: Since 85 > 3, we apply the division lemma to 85 and 3, to get

85 = 3 x 28 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 85 is 1

Notice that 1 = HCF(3,1) = HCF(85,3) .


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

Step 1: Since 445 > 1, we apply the division lemma to 445 and 1, to get

445 = 1 x 445 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 445 is 1

Notice that 1 = HCF(445,1) .
