HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 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 497, 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 497, 169 is 1.
HCF(497, 169) = 1
HCF of 497, 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 497, 169 is 1.
Highest Common Factor of 497,169 is 1
Step 1: Since 497 > 169, we apply the division lemma to 497 and 169, to get
497 = 169 x 2 + 159
Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 159 and 169, to get
169 = 159 x 1 + 10
Step 3: We consider the new divisor 159 and the new remainder 10, and apply the division lemma to get
159 = 10 x 15 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 169 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(159,10) = HCF(169,159) = HCF(497,169) .
