HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 259, 491, 47 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 259, 491, 47 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 259, 491, 47 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 259, 491, 47 is 1.
HCF(259, 491, 47) = 1
HCF of 259, 491, 47 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 259, 491, 47 is 1.
Highest Common Factor of 259,491,47 is 1
Step 1: Since 491 > 259, we apply the division lemma to 491 and 259, to get
491 = 259 x 1 + 232
Step 2: Since the reminder 259 ≠ 0, we apply division lemma to 232 and 259, to get
259 = 232 x 1 + 27
Step 3: We consider the new divisor 232 and the new remainder 27, and apply the division lemma to get
232 = 27 x 8 + 16
We consider the new divisor 27 and the new remainder 16,and apply the division lemma to get
27 = 16 x 1 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 259 and 491 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(232,27) = HCF(259,232) = HCF(491,259) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 47 > 1, we apply the division lemma to 47 and 1, to get
47 = 1 x 47 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 47 is 1
Notice that 1 = HCF(47,1) .
