HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 768, 512 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 768, 512 is 4 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 868, 768, 512 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 868, 768, 512 is 4.

HCF(868, 768, 512) = 4

HCF of 868, 768, 512 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 868, 768, 512 is 4.

Highest Common Factor of 868,768,512 using Euclid's algorithm

Highest Common Factor of 868,768,512 is 4

Step 1: Since 868 > 768, we apply the division lemma to 868 and 768, to get

868 = 768 x 1 + 100

Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 100 and 768, to get

768 = 100 x 7 + 68

Step 3: We consider the new divisor 100 and the new remainder 68, and apply the division lemma to get

100 = 68 x 1 + 32

We consider the new divisor 68 and the new remainder 32,and apply the division lemma to get

68 = 32 x 2 + 4

We consider the new divisor 32 and the new remainder 4,and apply the division lemma to get

32 = 4 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 868 and 768 is 4

Notice that 4 = HCF(32,4) = HCF(68,32) = HCF(100,68) = HCF(768,100) = HCF(868,768) .


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

Step 1: Since 512 > 4, we apply the division lemma to 512 and 4, to get

512 = 4 x 128 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 512 is 4

Notice that 4 = HCF(512,4) .
