HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 302, 459, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 302, 459, 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 302, 459, 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 302, 459, 491 is 1.
HCF(302, 459, 491) = 1
HCF of 302, 459, 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 302, 459, 491 is 1.
Highest Common Factor of 302,459,491 is 1
Step 1: Since 459 > 302, we apply the division lemma to 459 and 302, to get
459 = 302 x 1 + 157
Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 157 and 302, to get
302 = 157 x 1 + 145
Step 3: We consider the new divisor 157 and the new remainder 145, and apply the division lemma to get
157 = 145 x 1 + 12
We consider the new divisor 145 and the new remainder 12,and apply the division lemma to get
145 = 12 x 12 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 302 and 459 is 1
Notice that 1 = HCF(12,1) = HCF(145,12) = HCF(157,145) = HCF(302,157) = HCF(459,302) .
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) .
