HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 585 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 585 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 398, 585 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 398, 585 is 1.
HCF(398, 585) = 1
HCF of 398, 585 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 585 is 1.
Highest Common Factor of 398,585 is 1
Step 1: Since 585 > 398, we apply the division lemma to 585 and 398, to get
585 = 398 x 1 + 187
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 187 and 398, to get
398 = 187 x 2 + 24
Step 3: We consider the new divisor 187 and the new remainder 24, and apply the division lemma to get
187 = 24 x 7 + 19
We consider the new divisor 24 and the new remainder 19,and apply the division lemma to get
24 = 19 x 1 + 5
We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get
19 = 5 x 3 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 398 and 585 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(187,24) = HCF(398,187) = HCF(585,398) .
