HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 857 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 857 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 459, 857 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 459, 857 is 1.
HCF(459, 857) = 1
HCF of 459, 857 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 857 is 1.
Highest Common Factor of 459,857 is 1
Step 1: Since 857 > 459, we apply the division lemma to 857 and 459, to get
857 = 459 x 1 + 398
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 398 and 459, to get
459 = 398 x 1 + 61
Step 3: We consider the new divisor 398 and the new remainder 61, and apply the division lemma to get
398 = 61 x 6 + 32
We consider the new divisor 61 and the new remainder 32,and apply the division lemma to get
61 = 32 x 1 + 29
We consider the new divisor 32 and the new remainder 29,and apply the division lemma to get
32 = 29 x 1 + 3
We consider the new divisor 29 and the new remainder 3,and apply the division lemma to get
29 = 3 x 9 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 459 and 857 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(29,3) = HCF(32,29) = HCF(61,32) = HCF(398,61) = HCF(459,398) = HCF(857,459) .
