HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 8586, 3892 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 637, 8586, 3892 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 637, 8586, 3892 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 637, 8586, 3892 is 1.
HCF(637, 8586, 3892) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 637, 8586, 3892 is 1.
Step 1: Since 8586 > 637, we apply the division lemma to 8586 and 637, to get
8586 = 637 x 13 + 305
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 305 and 637, to get
637 = 305 x 2 + 27
Step 3: We consider the new divisor 305 and the new remainder 27, and apply the division lemma to get
305 = 27 x 11 + 8
We consider the new divisor 27 and the new remainder 8,and apply the division lemma to get
27 = 8 x 3 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 637 and 8586 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(27,8) = HCF(305,27) = HCF(637,305) = HCF(8586,637) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3892 > 1, we apply the division lemma to 3892 and 1, to get
3892 = 1 x 3892 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3892 is 1
Notice that 1 = HCF(3892,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
