HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 465 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 465 is 15 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 765, 465 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 765, 465 is 15.
HCF(765, 465) = 15
HCF of 765, 465 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 465 is 15.
Highest Common Factor of 765,465 is 15
Step 1: Since 765 > 465, we apply the division lemma to 765 and 465, to get
765 = 465 x 1 + 300
Step 2: Since the reminder 465 ≠ 0, we apply division lemma to 300 and 465, to get
465 = 300 x 1 + 165
Step 3: We consider the new divisor 300 and the new remainder 165, and apply the division lemma to get
300 = 165 x 1 + 135
We consider the new divisor 165 and the new remainder 135,and apply the division lemma to get
165 = 135 x 1 + 30
We consider the new divisor 135 and the new remainder 30,and apply the division lemma to get
135 = 30 x 4 + 15
We consider the new divisor 30 and the new remainder 15,and apply the division lemma to get
30 = 15 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 765 and 465 is 15
Notice that 15 = HCF(30,15) = HCF(135,30) = HCF(165,135) = HCF(300,165) = HCF(465,300) = HCF(765,465) .
