HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 5787 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 5787 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, 5787 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, 5787 is 3.
HCF(768, 5787) = 3
HCF of 768, 5787 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, 5787 is 3.
Highest Common Factor of 768,5787 is 3
Step 1: Since 5787 > 768, we apply the division lemma to 5787 and 768, to get
5787 = 768 x 7 + 411
Step 2: Since the reminder 768 ≠ 0, we apply division lemma to 411 and 768, to get
768 = 411 x 1 + 357
Step 3: We consider the new divisor 411 and the new remainder 357, and apply the division lemma to get
411 = 357 x 1 + 54
We consider the new divisor 357 and the new remainder 54,and apply the division lemma to get
357 = 54 x 6 + 33
We consider the new divisor 54 and the new remainder 33,and apply the division lemma to get
54 = 33 x 1 + 21
We consider the new divisor 33 and the new remainder 21,and apply the division lemma to get
33 = 21 x 1 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 768 and 5787 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) = HCF(54,33) = HCF(357,54) = HCF(411,357) = HCF(768,411) = HCF(5787,768) .
