HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 491, 3069 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 491, 3069 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, 3069 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, 3069 is 1.
HCF(491, 3069) = 1
HCF of 491, 3069 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, 3069 is 1.
Highest Common Factor of 491,3069 is 1
Step 1: Since 3069 > 491, we apply the division lemma to 3069 and 491, to get
3069 = 491 x 6 + 123
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 123 and 491, to get
491 = 123 x 3 + 122
Step 3: We consider the new divisor 123 and the new remainder 122, and apply the division lemma to get
123 = 122 x 1 + 1
We consider the new divisor 122 and the new remainder 1, and apply the division lemma to get
122 = 1 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 491 and 3069 is 1
Notice that 1 = HCF(122,1) = HCF(123,122) = HCF(491,123) = HCF(3069,491) .
