HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 205, 7797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 205, 7797 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 205, 7797 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 205, 7797 is 1.
HCF(205, 7797) = 1
HCF of 205, 7797 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 205, 7797 is 1.
Highest Common Factor of 205,7797 is 1
Step 1: Since 7797 > 205, we apply the division lemma to 7797 and 205, to get
7797 = 205 x 38 + 7
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 7 and 205, to get
205 = 7 x 29 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 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 205 and 7797 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(205,7) = HCF(7797,205) .
