HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 293, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 293, 491 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 293, 491 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 293, 491 is 1.
HCF(293, 491) = 1
HCF of 293, 491 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 293, 491 is 1.
Highest Common Factor of 293,491 is 1
Step 1: Since 491 > 293, we apply the division lemma to 491 and 293, to get
491 = 293 x 1 + 198
Step 2: Since the reminder 293 ≠ 0, we apply division lemma to 198 and 293, to get
293 = 198 x 1 + 95
Step 3: We consider the new divisor 198 and the new remainder 95, and apply the division lemma to get
198 = 95 x 2 + 8
We consider the new divisor 95 and the new remainder 8,and apply the division lemma to get
95 = 8 x 11 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 293 and 491 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(95,8) = HCF(198,95) = HCF(293,198) = HCF(491,293) .
