HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6721, 2180 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6721, 2180 is 1 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 6721, 2180 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 6721, 2180 is 1.
HCF(6721, 2180) = 1
HCF of 6721, 2180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6721, 2180 is 1.
Highest Common Factor of 6721,2180 is 1
Step 1: Since 6721 > 2180, we apply the division lemma to 6721 and 2180, to get
6721 = 2180 x 3 + 181
Step 2: Since the reminder 2180 ≠ 0, we apply division lemma to 181 and 2180, to get
2180 = 181 x 12 + 8
Step 3: We consider the new divisor 181 and the new remainder 8, and apply the division lemma to get
181 = 8 x 22 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6721 and 2180 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(181,8) = HCF(2180,181) = HCF(6721,2180) .
