HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 995, 571 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 995, 571 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 995, 571 is 1.
HCF(995, 571) = 1
HCF of 995, 571 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 995, 571 is 1.
Highest Common Factor of 995,571 is 1
Step 1: Since 995 > 571, we apply the division lemma to 995 and 571, to get
995 = 571 x 1 + 424
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 424 and 571, to get
571 = 424 x 1 + 147
Step 3: We consider the new divisor 424 and the new remainder 147, and apply the division lemma to get
424 = 147 x 2 + 130
We consider the new divisor 147 and the new remainder 130,and apply the division lemma to get
147 = 130 x 1 + 17
We consider the new divisor 130 and the new remainder 17,and apply the division lemma to get
130 = 17 x 7 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 995 and 571 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(130,17) = HCF(147,130) = HCF(424,147) = HCF(571,424) = HCF(995,571) .
