HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8215, 7898 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8215, 7898 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 8215, 7898 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 8215, 7898 is 1.
HCF(8215, 7898) = 1
HCF of 8215, 7898 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8215, 7898 is 1.
Highest Common Factor of 8215,7898 is 1
Step 1: Since 8215 > 7898, we apply the division lemma to 8215 and 7898, to get
8215 = 7898 x 1 + 317
Step 2: Since the reminder 7898 ≠ 0, we apply division lemma to 317 and 7898, to get
7898 = 317 x 24 + 290
Step 3: We consider the new divisor 317 and the new remainder 290, and apply the division lemma to get
317 = 290 x 1 + 27
We consider the new divisor 290 and the new remainder 27,and apply the division lemma to get
290 = 27 x 10 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8215 and 7898 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(290,27) = HCF(317,290) = HCF(7898,317) = HCF(8215,7898) .
