HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 38, 76, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 38, 76, 905 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 38, 76, 905 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 38, 76, 905 is 1.

HCF(38, 76, 905) = 1

HCF of 38, 76, 905 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 38, 76, 905 is 1.

Highest Common Factor of 38,76,905 using Euclid's algorithm

Highest Common Factor of 38,76,905 is 1

Step 1: Since 76 > 38, we apply the division lemma to 76 and 38, to get

76 = 38 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 38, the HCF of 38 and 76 is 38

Notice that 38 = HCF(76,38) .


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

Step 1: Since 905 > 38, we apply the division lemma to 905 and 38, to get

905 = 38 x 23 + 31

Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 31 and 38, to get

38 = 31 x 1 + 7

Step 3: We consider the new divisor 31 and the new remainder 7, and apply the division lemma to get

31 = 7 x 4 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 38 and 905 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(31,7) = HCF(38,31) = HCF(905,38) .
