HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 931, 427 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 381, 931, 427 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 381, 931, 427 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 381, 931, 427 is 1.

HCF(381, 931, 427) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 381, 931, 427 is 1.

Highest Common Factor of 381,931,427 using Euclid's algorithm

Highest Common Factor of 381,931,427 is 1

Step 1: Since 931 > 381, we apply the division lemma to 931 and 381, to get

931 = 381 x 2 + 169

Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 169 and 381, to get

381 = 169 x 2 + 43

Step 3: We consider the new divisor 169 and the new remainder 43, and apply the division lemma to get

169 = 43 x 3 + 40

We consider the new divisor 43 and the new remainder 40,and apply the division lemma to get

43 = 40 x 1 + 3

We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get

40 = 3 x 13 + 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 381 and 931 is 1

Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(43,40) = HCF(169,43) = HCF(381,169) = HCF(931,381) .

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

Step 1: Since 427 > 1, we apply the division lemma to 427 and 1, to get

427 = 1 x 427 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 427 is 1

Notice that 1 = HCF(427,1) .
