HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 85 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 570, 85 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, 85 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, 85 is 5.
HCF(570, 85) = 5
HCF of 570, 85 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, 85 is 5.
Highest Common Factor of 570,85 is 5
Step 1: Since 570 > 85, we apply the division lemma to 570 and 85, to get
570 = 85 x 6 + 60
Step 2: Since the reminder 85 ≠ 0, we apply division lemma to 60 and 85, to get
85 = 60 x 1 + 25
Step 3: We consider the new divisor 60 and the new remainder 25, and apply the division lemma to get
60 = 25 x 2 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 570 and 85 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(60,25) = HCF(85,60) = HCF(570,85) .
