HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 753, 687 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 753, 687 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 831, 753, 687 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 831, 753, 687 is 3.
HCF(831, 753, 687) = 3
HCF of 831, 753, 687 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 753, 687 is 3.
Highest Common Factor of 831,753,687 is 3
Step 1: Since 831 > 753, we apply the division lemma to 831 and 753, to get
831 = 753 x 1 + 78
Step 2: Since the reminder 753 ≠ 0, we apply division lemma to 78 and 753, to get
753 = 78 x 9 + 51
Step 3: We consider the new divisor 78 and the new remainder 51, and apply the division lemma to get
78 = 51 x 1 + 27
We consider the new divisor 51 and the new remainder 27,and apply the division lemma to get
51 = 27 x 1 + 24
We consider the new divisor 27 and the new remainder 24,and apply the division lemma to get
27 = 24 x 1 + 3
We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 753 is 3
Notice that 3 = HCF(24,3) = HCF(27,24) = HCF(51,27) = HCF(78,51) = HCF(753,78) = HCF(831,753) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 687 > 3, we apply the division lemma to 687 and 3, to get
687 = 3 x 229 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 687 is 3
Notice that 3 = HCF(687,3) .
