HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 9399, 8898 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 645, 9399, 8898 is 3 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 645, 9399, 8898 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 645, 9399, 8898 is 3.

HCF(645, 9399, 8898) = 3

HCF of 645, 9399, 8898 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 645, 9399, 8898 is 3.

Highest Common Factor of 645,9399,8898 using Euclid's algorithm

Highest Common Factor of 645,9399,8898 is 3

Step 1: Since 9399 > 645, we apply the division lemma to 9399 and 645, to get

9399 = 645 x 14 + 369

Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 369 and 645, to get

645 = 369 x 1 + 276

Step 3: We consider the new divisor 369 and the new remainder 276, and apply the division lemma to get

369 = 276 x 1 + 93

We consider the new divisor 276 and the new remainder 93,and apply the division lemma to get

276 = 93 x 2 + 90

We consider the new divisor 93 and the new remainder 90,and apply the division lemma to get

93 = 90 x 1 + 3

We consider the new divisor 90 and the new remainder 3,and apply the division lemma to get

90 = 3 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 645 and 9399 is 3

Notice that 3 = HCF(90,3) = HCF(93,90) = HCF(276,93) = HCF(369,276) = HCF(645,369) = HCF(9399,645) .


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

Step 1: Since 8898 > 3, we apply the division lemma to 8898 and 3, to get

8898 = 3 x 2966 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 8898 is 3

Notice that 3 = HCF(8898,3) .
