HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 130, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 130, 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 130, 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 130, 491 is 1.
HCF(130, 491) = 1
HCF of 130, 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 130, 491 is 1.
Highest Common Factor of 130,491 is 1
Step 1: Since 491 > 130, we apply the division lemma to 491 and 130, to get
491 = 130 x 3 + 101
Step 2: Since the reminder 130 ≠ 0, we apply division lemma to 101 and 130, to get
130 = 101 x 1 + 29
Step 3: We consider the new divisor 101 and the new remainder 29, and apply the division lemma to get
101 = 29 x 3 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 130 and 491 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(101,29) = HCF(130,101) = HCF(491,130) .
