HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 934, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 393, 934, 957 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 393, 934, 957 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 393, 934, 957 is 1.

HCF(393, 934, 957) = 1

HCF of 393, 934, 957 using Euclid's algorithm

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

Highest common factor (HCF) of 393, 934, 957 is 1.

Highest Common Factor of 393,934,957 using Euclid's algorithm

Highest Common Factor of 393,934,957 is 1

Step 1: Since 934 > 393, we apply the division lemma to 934 and 393, to get

934 = 393 x 2 + 148

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 148 and 393, to get

393 = 148 x 2 + 97

Step 3: We consider the new divisor 148 and the new remainder 97, and apply the division lemma to get

148 = 97 x 1 + 51

We consider the new divisor 97 and the new remainder 51,and apply the division lemma to get

97 = 51 x 1 + 46

We consider the new divisor 51 and the new remainder 46,and apply the division lemma to get

51 = 46 x 1 + 5

We consider the new divisor 46 and the new remainder 5,and apply the division lemma to get

46 = 5 x 9 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 393 and 934 is 1

Notice that 1 = HCF(5,1) = HCF(46,5) = HCF(51,46) = HCF(97,51) = HCF(148,97) = HCF(393,148) = HCF(934,393) .

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

Step 1: Since 957 > 1, we apply the division lemma to 957 and 1, to get

957 = 1 x 957 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 957 is 1

Notice that 1 = HCF(957,1) .
