HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 1831 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 468, 1831 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 468, 1831 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 468, 1831 is 1.
HCF(468, 1831) = 1
HCF of 468, 1831 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 468, 1831 is 1.
Highest Common Factor of 468,1831 is 1
Step 1: Since 1831 > 468, we apply the division lemma to 1831 and 468, to get
1831 = 468 x 3 + 427
Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 427 and 468, to get
468 = 427 x 1 + 41
Step 3: We consider the new divisor 427 and the new remainder 41, and apply the division lemma to get
427 = 41 x 10 + 17
We consider the new divisor 41 and the new remainder 17,and apply the division lemma to get
41 = 17 x 2 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 468 and 1831 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(41,17) = HCF(427,41) = HCF(468,427) = HCF(1831,468) .
