HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 205 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 570, 205 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 570, 205 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 570, 205 is 5.
HCF(570, 205) = 5
HCF of 570, 205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 570, 205 is 5.
Highest Common Factor of 570,205 is 5
Step 1: Since 570 > 205, we apply the division lemma to 570 and 205, to get
570 = 205 x 2 + 160
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 160 and 205, to get
205 = 160 x 1 + 45
Step 3: We consider the new divisor 160 and the new remainder 45, and apply the division lemma to get
160 = 45 x 3 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 570 and 205 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(160,45) = HCF(205,160) = HCF(570,205) .
