HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 9149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 9149 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 491, 9149 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 491, 9149 is 1.
HCF(491, 9149) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 9149 is 1.
Step 1: Since 9149 > 491, we apply the division lemma to 9149 and 491, to get
9149 = 491 x 18 + 311
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 311 and 491, to get
491 = 311 x 1 + 180
Step 3: We consider the new divisor 311 and the new remainder 180, and apply the division lemma to get
311 = 180 x 1 + 131
We consider the new divisor 180 and the new remainder 131,and apply the division lemma to get
180 = 131 x 1 + 49
We consider the new divisor 131 and the new remainder 49,and apply the division lemma to get
131 = 49 x 2 + 33
We consider the new divisor 49 and the new remainder 33,and apply the division lemma to get
49 = 33 x 1 + 16
We consider the new divisor 33 and the new remainder 16,and apply the division lemma to get
33 = 16 x 2 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 9149 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(49,33) = HCF(131,49) = HCF(180,131) = HCF(311,180) = HCF(491,311) = HCF(9149,491) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
