HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 765 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 993, 765 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 993, 765 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 993, 765 is 3.
HCF(993, 765) = 3
HCF of 993, 765 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 993, 765 is 3.
Highest Common Factor of 993,765 is 3
Step 1: Since 993 > 765, we apply the division lemma to 993 and 765, to get
993 = 765 x 1 + 228
Step 2: Since the reminder 765 ≠ 0, we apply division lemma to 228 and 765, to get
765 = 228 x 3 + 81
Step 3: We consider the new divisor 228 and the new remainder 81, and apply the division lemma to get
228 = 81 x 2 + 66
We consider the new divisor 81 and the new remainder 66,and apply the division lemma to get
81 = 66 x 1 + 15
We consider the new divisor 66 and the new remainder 15,and apply the division lemma to get
66 = 15 x 4 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 993 and 765 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(66,15) = HCF(81,66) = HCF(228,81) = HCF(765,228) = HCF(993,765) .
