HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 334, 243, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 334, 243, 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 334, 243, 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 334, 243, 491 is 1.
HCF(334, 243, 491) = 1
HCF of 334, 243, 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 334, 243, 491 is 1.
Highest Common Factor of 334,243,491 is 1
Step 1: Since 334 > 243, we apply the division lemma to 334 and 243, to get
334 = 243 x 1 + 91
Step 2: Since the reminder 243 ≠ 0, we apply division lemma to 91 and 243, to get
243 = 91 x 2 + 61
Step 3: We consider the new divisor 91 and the new remainder 61, and apply the division lemma to get
91 = 61 x 1 + 30
We consider the new divisor 61 and the new remainder 30,and apply the division lemma to get
61 = 30 x 2 + 1
We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 334 and 243 is 1
Notice that 1 = HCF(30,1) = HCF(61,30) = HCF(91,61) = HCF(243,91) = HCF(334,243) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 491 > 1, we apply the division lemma to 491 and 1, to get
491 = 1 x 491 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 491 is 1
Notice that 1 = HCF(491,1) .
