HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 795, 443 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 795, 443 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, 795, 443 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, 795, 443 is 1.
HCF(491, 795, 443) = 1
HCF of 491, 795, 443 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 491, 795, 443 is 1.
Highest Common Factor of 491,795,443 is 1
Step 1: Since 795 > 491, we apply the division lemma to 795 and 491, to get
795 = 491 x 1 + 304
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 304 and 491, to get
491 = 304 x 1 + 187
Step 3: We consider the new divisor 304 and the new remainder 187, and apply the division lemma to get
304 = 187 x 1 + 117
We consider the new divisor 187 and the new remainder 117,and apply the division lemma to get
187 = 117 x 1 + 70
We consider the new divisor 117 and the new remainder 70,and apply the division lemma to get
117 = 70 x 1 + 47
We consider the new divisor 70 and the new remainder 47,and apply the division lemma to get
70 = 47 x 1 + 23
We consider the new divisor 47 and the new remainder 23,and apply the division lemma to get
47 = 23 x 2 + 1
We consider the new divisor 23 and the new remainder 1,and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 795 is 1
Notice that 1 = HCF(23,1) = HCF(47,23) = HCF(70,47) = HCF(117,70) = HCF(187,117) = HCF(304,187) = HCF(491,304) = HCF(795,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 443 > 1, we apply the division lemma to 443 and 1, to get
443 = 1 x 443 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 443 is 1
Notice that 1 = HCF(443,1) .
