HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 968, 804, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 644, 968, 804, 939 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 644, 968, 804, 939 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 644, 968, 804, 939 is 1.

HCF(644, 968, 804, 939) = 1

HCF of 644, 968, 804, 939 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 644, 968, 804, 939 is 1.

Highest Common Factor of 644,968,804,939 using Euclid's algorithm

Highest Common Factor of 644,968,804,939 is 1

Step 1: Since 968 > 644, we apply the division lemma to 968 and 644, to get

968 = 644 x 1 + 324

Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 324 and 644, to get

644 = 324 x 1 + 320

Step 3: We consider the new divisor 324 and the new remainder 320, and apply the division lemma to get

324 = 320 x 1 + 4

We consider the new divisor 320 and the new remainder 4, and apply the division lemma to get

320 = 4 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 644 and 968 is 4

Notice that 4 = HCF(320,4) = HCF(324,320) = HCF(644,324) = HCF(968,644) .

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

Step 1: Since 804 > 4, we apply the division lemma to 804 and 4, to get

804 = 4 x 201 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 804 is 4

Notice that 4 = HCF(804,4) .

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

Step 1: Since 939 > 4, we apply the division lemma to 939 and 4, to get

939 = 4 x 234 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: 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 4 and 939 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(939,4) .
