HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 16479 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 16479 is 3 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, 16479 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, 16479 is 3.
HCF(768, 16479) = 3
HCF of 768, 16479 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 16479 is 3.
Highest Common Factor of 768,16479 is 3
Step 1: Since 16479 > 768, we apply the division lemma to 16479 and 768, to get
16479 = 768 x 21 + 351
Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 351 and 768, to get
768 = 351 x 2 + 66
Step 3: We consider the new divisor 351 and the new remainder 66, and apply the division lemma to get
351 = 66 x 5 + 21
We consider the new divisor 66 and the new remainder 21,and apply the division lemma to get
66 = 21 x 3 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 768 and 16479 is 3
Notice that 3 = HCF(21,3) = HCF(66,21) = HCF(351,66) = HCF(768,351) = HCF(16479,768) .
