HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 21481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 21481 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 180, 21481 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 180, 21481 is 1.
HCF(180, 21481) = 1
HCF of 180, 21481 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 21481 is 1.
Highest Common Factor of 180,21481 is 1
Step 1: Since 21481 > 180, we apply the division lemma to 21481 and 180, to get
21481 = 180 x 119 + 61
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 61 and 180, to get
180 = 61 x 2 + 58
Step 3: We consider the new divisor 61 and the new remainder 58, and apply the division lemma to get
61 = 58 x 1 + 3
We consider the new divisor 58 and the new remainder 3,and apply the division lemma to get
58 = 3 x 19 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 180 and 21481 is 1
Notice that 1 = HCF(3,1) = HCF(58,3) = HCF(61,58) = HCF(180,61) = HCF(21481,180) .
