HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 40, 24, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 65, 40, 24, 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 65, 40, 24, 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 65, 40, 24, 957 is 1.

HCF(65, 40, 24, 957) = 1

HCF of 65, 40, 24, 957 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 65, 40, 24, 957 is 1.

Highest Common Factor of 65,40,24,957 using Euclid's algorithm

Highest Common Factor of 65,40,24,957 is 1

Step 1: Since 65 > 40, we apply the division lemma to 65 and 40, to get

65 = 40 x 1 + 25

Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 25 and 40, to get

40 = 25 x 1 + 15

Step 3: We consider the new divisor 25 and the new remainder 15, and apply the division lemma to get

25 = 15 x 1 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 65 and 40 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(40,25) = HCF(65,40) .

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

Step 1: Since 24 > 5, we apply the division lemma to 24 and 5, to get

24 = 5 x 4 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: 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 5 and 24 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) .

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) .
