HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2638, 2317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 2638, 2317 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 2638, 2317 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 2638, 2317 is 1.
HCF(2638, 2317) = 1
HCF of 2638, 2317 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2638, 2317 is 1.
Highest Common Factor of 2638,2317 is 1
Step 1: Since 2638 > 2317, we apply the division lemma to 2638 and 2317, to get
2638 = 2317 x 1 + 321
Step 2: Since the reminder 2317 ≠ 0, we apply division lemma to 321 and 2317, to get
2317 = 321 x 7 + 70
Step 3: We consider the new divisor 321 and the new remainder 70, and apply the division lemma to get
321 = 70 x 4 + 41
We consider the new divisor 70 and the new remainder 41,and apply the division lemma to get
70 = 41 x 1 + 29
We consider the new divisor 41 and the new remainder 29,and apply the division lemma to get
41 = 29 x 1 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 2638 and 2317 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(70,41) = HCF(321,70) = HCF(2317,321) = HCF(2638,2317) .
