HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 389, 148, 940 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 389, 148, 940 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 389, 148, 940 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 389, 148, 940 is 1.

HCF(389, 148, 940) = 1

HCF of 389, 148, 940 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 389, 148, 940 is 1.

Highest Common Factor of 389,148,940 using Euclid's algorithm

Highest Common Factor of 389,148,940 is 1

Step 1: Since 389 > 148, we apply the division lemma to 389 and 148, to get

389 = 148 x 2 + 93

Step 2: Since the reminder 148 ≠ 0, we apply division lemma to 93 and 148, to get

148 = 93 x 1 + 55

Step 3: We consider the new divisor 93 and the new remainder 55, and apply the division lemma to get

93 = 55 x 1 + 38

We consider the new divisor 55 and the new remainder 38,and apply the division lemma to get

55 = 38 x 1 + 17

We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get

38 = 17 x 2 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 389 and 148 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(55,38) = HCF(93,55) = HCF(148,93) = HCF(389,148) .

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

Step 1: Since 940 > 1, we apply the division lemma to 940 and 1, to get

940 = 1 x 940 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 940 is 1

Notice that 1 = HCF(940,1) .
