HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 585 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 585 is 5 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 805, 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 805, 585 is 5.
HCF(805, 585) = 5
HCF of 805, 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 805, 585 is 5.
Highest Common Factor of 805,585 is 5
Step 1: Since 805 > 585, we apply the division lemma to 805 and 585, to get
805 = 585 x 1 + 220
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 220 and 585, to get
585 = 220 x 2 + 145
Step 3: We consider the new divisor 220 and the new remainder 145, and apply the division lemma to get
220 = 145 x 1 + 75
We consider the new divisor 145 and the new remainder 75,and apply the division lemma to get
145 = 75 x 1 + 70
We consider the new divisor 75 and the new remainder 70,and apply the division lemma to get
75 = 70 x 1 + 5
We consider the new divisor 70 and the new remainder 5,and apply the division lemma to get
70 = 5 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 805 and 585 is 5
Notice that 5 = HCF(70,5) = HCF(75,70) = HCF(145,75) = HCF(220,145) = HCF(585,220) = HCF(805,585) .
