HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 586 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 586 is 2 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 438, 586 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 438, 586 is 2.
HCF(438, 586) = 2
HCF of 438, 586 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 586 is 2.
Highest Common Factor of 438,586 is 2
Step 1: Since 586 > 438, we apply the division lemma to 586 and 438, to get
586 = 438 x 1 + 148
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 148 and 438, to get
438 = 148 x 2 + 142
Step 3: We consider the new divisor 148 and the new remainder 142, and apply the division lemma to get
148 = 142 x 1 + 6
We consider the new divisor 142 and the new remainder 6,and apply the division lemma to get
142 = 6 x 23 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 438 and 586 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(142,6) = HCF(148,142) = HCF(438,148) = HCF(586,438) .
