HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 637, 82 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 637, 82 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 436, 637, 82 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 436, 637, 82 is 1.
HCF(436, 637, 82) = 1
HCF of 436, 637, 82 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 637, 82 is 1.
Highest Common Factor of 436,637,82 is 1
Step 1: Since 637 > 436, we apply the division lemma to 637 and 436, to get
637 = 436 x 1 + 201
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 201 and 436, to get
436 = 201 x 2 + 34
Step 3: We consider the new divisor 201 and the new remainder 34, and apply the division lemma to get
201 = 34 x 5 + 31
We consider the new divisor 34 and the new remainder 31,and apply the division lemma to get
34 = 31 x 1 + 3
We consider the new divisor 31 and the new remainder 3,and apply the division lemma to get
31 = 3 x 10 + 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 436 and 637 is 1
Notice that 1 = HCF(3,1) = HCF(31,3) = HCF(34,31) = HCF(201,34) = HCF(436,201) = HCF(637,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 82 > 1, we apply the division lemma to 82 and 1, to get
82 = 1 x 82 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 82 is 1
Notice that 1 = HCF(82,1) .
