HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 792, 68 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 792, 68 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 792, 68 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 792, 68 is 4.

HCF(792, 68) = 4

HCF of 792, 68 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 792, 68 is 4.

Highest Common Factor of 792,68 using Euclid's algorithm

Highest Common Factor of 792,68 is 4

Step 1: Since 792 > 68, we apply the division lemma to 792 and 68, to get

792 = 68 x 11 + 44

Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 44 and 68, to get

68 = 44 x 1 + 24

Step 3: We consider the new divisor 44 and the new remainder 24, and apply the division lemma to get

44 = 24 x 1 + 20

We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get

24 = 20 x 1 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 792 and 68 is 4

Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(68,44) = HCF(792,68) .
