HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 169 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, 169 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, 169 is 1.
HCF(791, 169) = 1
HCF of 791, 169 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, 169 is 1.
Highest Common Factor of 791,169 is 1
Step 1: Since 791 > 169, we apply the division lemma to 791 and 169, to get
791 = 169 x 4 + 115
Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 115 and 169, to get
169 = 115 x 1 + 54
Step 3: We consider the new divisor 115 and the new remainder 54, and apply the division lemma to get
115 = 54 x 2 + 7
We consider the new divisor 54 and the new remainder 7,and apply the division lemma to get
54 = 7 x 7 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 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 791 and 169 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(54,7) = HCF(115,54) = HCF(169,115) = HCF(791,169) .
