HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 405, 797 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 405, 797 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 405, 797 is 1.
HCF(405, 797) = 1
HCF of 405, 797 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 405, 797 is 1.
Highest Common Factor of 405,797 is 1
Step 1: Since 797 > 405, we apply the division lemma to 797 and 405, to get
797 = 405 x 1 + 392
Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 392 and 405, to get
405 = 392 x 1 + 13
Step 3: We consider the new divisor 392 and the new remainder 13, and apply the division lemma to get
392 = 13 x 30 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 405 and 797 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(392,13) = HCF(405,392) = HCF(797,405) .
