HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 8193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 8193 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, 8193 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, 8193 is 1.
HCF(791, 8193) = 1
HCF of 791, 8193 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, 8193 is 1.
Highest Common Factor of 791,8193 is 1
Step 1: Since 8193 > 791, we apply the division lemma to 8193 and 791, to get
8193 = 791 x 10 + 283
Step 2: Since the reminder 791 ≠ 0, we apply division lemma to 283 and 791, to get
791 = 283 x 2 + 225
Step 3: We consider the new divisor 283 and the new remainder 225, and apply the division lemma to get
283 = 225 x 1 + 58
We consider the new divisor 225 and the new remainder 58,and apply the division lemma to get
225 = 58 x 3 + 51
We consider the new divisor 58 and the new remainder 51,and apply the division lemma to get
58 = 51 x 1 + 7
We consider the new divisor 51 and the new remainder 7,and apply the division lemma to get
51 = 7 x 7 + 2
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 791 and 8193 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(51,7) = HCF(58,51) = HCF(225,58) = HCF(283,225) = HCF(791,283) = HCF(8193,791) .
