HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9929, 2498, 81330 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9929, 2498, 81330 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 9929, 2498, 81330 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 9929, 2498, 81330 is 1.
HCF(9929, 2498, 81330) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9929, 2498, 81330 is 1.
Step 1: Since 9929 > 2498, we apply the division lemma to 9929 and 2498, to get
9929 = 2498 x 3 + 2435
Step 2: Since the reminder 2498 ≠ 0, we apply division lemma to 2435 and 2498, to get
2498 = 2435 x 1 + 63
Step 3: We consider the new divisor 2435 and the new remainder 63, and apply the division lemma to get
2435 = 63 x 38 + 41
We consider the new divisor 63 and the new remainder 41,and apply the division lemma to get
63 = 41 x 1 + 22
We consider the new divisor 41 and the new remainder 22,and apply the division lemma to get
41 = 22 x 1 + 19
We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get
22 = 19 x 1 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 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 9929 and 2498 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(41,22) = HCF(63,41) = HCF(2435,63) = HCF(2498,2435) = HCF(9929,2498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81330 > 1, we apply the division lemma to 81330 and 1, to get
81330 = 1 x 81330 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 81330 is 1
Notice that 1 = HCF(81330,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
