HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 499, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 499, 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 499, 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 499, 797 is 1.
HCF(499, 797) = 1
HCF of 499, 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 499, 797 is 1.
Highest Common Factor of 499,797 is 1
Step 1: Since 797 > 499, we apply the division lemma to 797 and 499, to get
797 = 499 x 1 + 298
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 298 and 499, to get
499 = 298 x 1 + 201
Step 3: We consider the new divisor 298 and the new remainder 201, and apply the division lemma to get
298 = 201 x 1 + 97
We consider the new divisor 201 and the new remainder 97,and apply the division lemma to get
201 = 97 x 2 + 7
We consider the new divisor 97 and the new remainder 7,and apply the division lemma to get
97 = 7 x 13 + 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 499 and 797 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(97,7) = HCF(201,97) = HCF(298,201) = HCF(499,298) = HCF(797,499) .
