HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 31441 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 485, 31441 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 485, 31441 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 485, 31441 is 1.
HCF(485, 31441) = 1
HCF of 485, 31441 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 485, 31441 is 1.
Highest Common Factor of 485,31441 is 1
Step 1: Since 31441 > 485, we apply the division lemma to 31441 and 485, to get
31441 = 485 x 64 + 401
Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 401 and 485, to get
485 = 401 x 1 + 84
Step 3: We consider the new divisor 401 and the new remainder 84, and apply the division lemma to get
401 = 84 x 4 + 65
We consider the new divisor 84 and the new remainder 65,and apply the division lemma to get
84 = 65 x 1 + 19
We consider the new divisor 65 and the new remainder 19,and apply the division lemma to get
65 = 19 x 3 + 8
We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get
19 = 8 x 2 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 31441 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(65,19) = HCF(84,65) = HCF(401,84) = HCF(485,401) = HCF(31441,485) .
