HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 687, 84831 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 687, 84831 is 3 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 687, 84831 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 687, 84831 is 3.
HCF(687, 84831) = 3
HCF of 687, 84831 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 687, 84831 is 3.
Highest Common Factor of 687,84831 is 3
Step 1: Since 84831 > 687, we apply the division lemma to 84831 and 687, to get
84831 = 687 x 123 + 330
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 330 and 687, to get
687 = 330 x 2 + 27
Step 3: We consider the new divisor 330 and the new remainder 27, and apply the division lemma to get
330 = 27 x 12 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 687 and 84831 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(330,27) = HCF(687,330) = HCF(84831,687) .
