HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 356, 459, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 356, 459, 23 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 356, 459, 23 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 356, 459, 23 is 1.
HCF(356, 459, 23) = 1
HCF of 356, 459, 23 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 356, 459, 23 is 1.
Highest Common Factor of 356,459,23 is 1
Step 1: Since 459 > 356, we apply the division lemma to 459 and 356, to get
459 = 356 x 1 + 103
Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 103 and 356, to get
356 = 103 x 3 + 47
Step 3: We consider the new divisor 103 and the new remainder 47, and apply the division lemma to get
103 = 47 x 2 + 9
We consider the new divisor 47 and the new remainder 9,and apply the division lemma to get
47 = 9 x 5 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 356 and 459 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(47,9) = HCF(103,47) = HCF(356,103) = HCF(459,356) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 23 > 1, we apply the division lemma to 23 and 1, 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 1 and 23 is 1
Notice that 1 = HCF(23,1) .
