HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 471, 180 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 471, 180 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 82, 471, 180 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 82, 471, 180 is 1.
HCF(82, 471, 180) = 1
HCF of 82, 471, 180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 82, 471, 180 is 1.
Highest Common Factor of 82,471,180 is 1
Step 1: Since 471 > 82, we apply the division lemma to 471 and 82, to get
471 = 82 x 5 + 61
Step 2: Since the reminder 82 ≠ 0, we apply division lemma to 61 and 82, to get
82 = 61 x 1 + 21
Step 3: We consider the new divisor 61 and the new remainder 21, and apply the division lemma to get
61 = 21 x 2 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 82 and 471 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(61,21) = HCF(82,61) = HCF(471,82) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 180 > 1, we apply the division lemma to 180 and 1, to get
180 = 1 x 180 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 180 is 1
Notice that 1 = HCF(180,1) .
