HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 6498 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 6498 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 791, 6498 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 791, 6498 is 1.
HCF(791, 6498) = 1
HCF of 791, 6498 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 6498 is 1.
Highest Common Factor of 791,6498 is 1
Step 1: Since 6498 > 791, we apply the division lemma to 6498 and 791, to get
6498 = 791 x 8 + 170
Step 2: Since the reminder 791 ≠ 0, we apply division lemma to 170 and 791, to get
791 = 170 x 4 + 111
Step 3: We consider the new divisor 170 and the new remainder 111, and apply the division lemma to get
170 = 111 x 1 + 59
We consider the new divisor 111 and the new remainder 59,and apply the division lemma to get
111 = 59 x 1 + 52
We consider the new divisor 59 and the new remainder 52,and apply the division lemma to get
59 = 52 x 1 + 7
We consider the new divisor 52 and the new remainder 7,and apply the division lemma to get
52 = 7 x 7 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 6498 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(52,7) = HCF(59,52) = HCF(111,59) = HCF(170,111) = HCF(791,170) = HCF(6498,791) .
