HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2181, 4400 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2181, 4400 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 2181, 4400 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 2181, 4400 is 1.
HCF(2181, 4400) = 1
HCF of 2181, 4400 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2181, 4400 is 1.
Highest Common Factor of 2181,4400 is 1
Step 1: Since 4400 > 2181, we apply the division lemma to 4400 and 2181, to get
4400 = 2181 x 2 + 38
Step 2: Since the reminder 2181 ≠ 0, we apply division lemma to 38 and 2181, to get
2181 = 38 x 57 + 15
Step 3: We consider the new divisor 38 and the new remainder 15, and apply the division lemma to get
38 = 15 x 2 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2181 and 4400 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(38,15) = HCF(2181,38) = HCF(4400,2181) .
