HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 66, 389, 894 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 65, 66, 389, 894 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 65, 66, 389, 894 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 65, 66, 389, 894 is 1.

HCF(65, 66, 389, 894) = 1

HCF of 65, 66, 389, 894 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 65, 66, 389, 894 is 1.

Highest Common Factor of 65,66,389,894 using Euclid's algorithm

Highest Common Factor of 65,66,389,894 is 1

Step 1: Since 66 > 65, we apply the division lemma to 66 and 65, to get

66 = 65 x 1 + 1

Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 1 and 65, to get

65 = 1 x 65 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 65 and 66 is 1

Notice that 1 = HCF(65,1) = HCF(66,65) .


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

Step 1: Since 389 > 1, we apply the division lemma to 389 and 1, to get

389 = 1 x 389 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 389 is 1

Notice that 1 = HCF(389,1) .


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

Step 1: Since 894 > 1, we apply the division lemma to 894 and 1, to get

894 = 1 x 894 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 894 is 1

Notice that 1 = HCF(894,1) .
