HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 285, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 285, 631 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 285, 631 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 285, 631 is 1.
HCF(285, 631) = 1
HCF of 285, 631 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 285, 631 is 1.
Highest Common Factor of 285,631 is 1
Step 1: Since 631 > 285, we apply the division lemma to 631 and 285, to get
631 = 285 x 2 + 61
Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 61 and 285, to get
285 = 61 x 4 + 41
Step 3: We consider the new divisor 61 and the new remainder 41, and apply the division lemma to get
61 = 41 x 1 + 20
We consider the new divisor 41 and the new remainder 20,and apply the division lemma to get
41 = 20 x 2 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 285 and 631 is 1
Notice that 1 = HCF(20,1) = HCF(41,20) = HCF(61,41) = HCF(285,61) = HCF(631,285) .
