HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 458, 579 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 458, 579 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 458, 579 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 458, 579 is 1.
HCF(458, 579) = 1
HCF of 458, 579 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 458, 579 is 1.
Highest Common Factor of 458,579 is 1
Step 1: Since 579 > 458, we apply the division lemma to 579 and 458, to get
579 = 458 x 1 + 121
Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 121 and 458, to get
458 = 121 x 3 + 95
Step 3: We consider the new divisor 121 and the new remainder 95, and apply the division lemma to get
121 = 95 x 1 + 26
We consider the new divisor 95 and the new remainder 26,and apply the division lemma to get
95 = 26 x 3 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 458 and 579 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(95,26) = HCF(121,95) = HCF(458,121) = HCF(579,458) .
