HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 34, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 34, 485 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, 34, 485 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, 34, 485 is 1.
HCF(82, 34, 485) = 1
HCF of 82, 34, 485 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, 34, 485 is 1.
Highest Common Factor of 82,34,485 is 1
Step 1: Since 82 > 34, we apply the division lemma to 82 and 34, to get
82 = 34 x 2 + 14
Step 2: Since the reminder 34 ≠ 0, we apply division lemma to 14 and 34, to get
34 = 14 x 2 + 6
Step 3: We consider the new divisor 14 and the new remainder 6, and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 82 and 34 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(82,34) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 2, we apply the division lemma to 485 and 2, to get
485 = 2 x 242 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 485 is 1
Notice that 1 = HCF(2,1) = HCF(485,2) .
