HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 68636 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 68636 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 768, 68636 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 768, 68636 is 4.
HCF(768, 68636) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 68636 is 4.
Step 1: Since 68636 > 768, we apply the division lemma to 68636 and 768, to get
68636 = 768 x 89 + 284
Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 284 and 768, to get
768 = 284 x 2 + 200
Step 3: We consider the new divisor 284 and the new remainder 200, and apply the division lemma to get
284 = 200 x 1 + 84
We consider the new divisor 200 and the new remainder 84,and apply the division lemma to get
200 = 84 x 2 + 32
We consider the new divisor 84 and the new remainder 32,and apply the division lemma to get
84 = 32 x 2 + 20
We consider the new divisor 32 and the new remainder 20,and apply the division lemma to get
32 = 20 x 1 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 768 and 68636 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(84,32) = HCF(200,84) = HCF(284,200) = HCF(768,284) = HCF(68636,768) .
Here are some samples of HCF using Euclid's Algorithm calculations.
