HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 394, 893, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 394, 893, 309 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 394, 893, 309 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 394, 893, 309 is 1.

HCF(394, 893, 309) = 1

HCF of 394, 893, 309 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 394, 893, 309 is 1.

Highest Common Factor of 394,893,309 using Euclid's algorithm

Highest Common Factor of 394,893,309 is 1

Step 1: Since 893 > 394, we apply the division lemma to 893 and 394, to get

893 = 394 x 2 + 105

Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 105 and 394, to get

394 = 105 x 3 + 79

Step 3: We consider the new divisor 105 and the new remainder 79, and apply the division lemma to get

105 = 79 x 1 + 26

We consider the new divisor 79 and the new remainder 26,and apply the division lemma to get

79 = 26 x 3 + 1

We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get

26 = 1 x 26 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 394 and 893 is 1

Notice that 1 = HCF(26,1) = HCF(79,26) = HCF(105,79) = HCF(394,105) = HCF(893,394) .


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

Step 1: Since 309 > 1, we apply the division lemma to 309 and 1, to get

309 = 1 x 309 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 309 is 1

Notice that 1 = HCF(309,1) .
