HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 122, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 122, 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 605, 122, 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 605, 122, 797 is 1.
HCF(605, 122, 797) = 1
HCF of 605, 122, 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 605, 122, 797 is 1.
Highest Common Factor of 605,122,797 is 1
Step 1: Since 605 > 122, we apply the division lemma to 605 and 122, to get
605 = 122 x 4 + 117
Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 117 and 122, to get
122 = 117 x 1 + 5
Step 3: We consider the new divisor 117 and the new remainder 5, and apply the division lemma to get
117 = 5 x 23 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 605 and 122 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(117,5) = HCF(122,117) = HCF(605,122) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 797 > 1, we apply the division lemma to 797 and 1, to get
797 = 1 x 797 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 797 is 1
Notice that 1 = HCF(797,1) .
