HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 2620 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 2620 is 5 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 165, 2620 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 165, 2620 is 5.
HCF(165, 2620) = 5
HCF of 165, 2620 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 2620 is 5.
Highest Common Factor of 165,2620 is 5
Step 1: Since 2620 > 165, we apply the division lemma to 2620 and 165, to get
2620 = 165 x 15 + 145
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 145 and 165, to get
165 = 145 x 1 + 20
Step 3: We consider the new divisor 145 and the new remainder 20, and apply the division lemma to get
145 = 20 x 7 + 5
We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 165 and 2620 is 5
Notice that 5 = HCF(20,5) = HCF(145,20) = HCF(165,145) = HCF(2620,165) .
