HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 579, 786, 831 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 579, 786, 831 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 579, 786, 831 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 579, 786, 831 is 3.
HCF(579, 786, 831) = 3
HCF of 579, 786, 831 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 579, 786, 831 is 3.
Highest Common Factor of 579,786,831 is 3
Step 1: Since 786 > 579, we apply the division lemma to 786 and 579, to get
786 = 579 x 1 + 207
Step 2: Since the reminder 579 ≠ 0, we apply division lemma to 207 and 579, to get
579 = 207 x 2 + 165
Step 3: We consider the new divisor 207 and the new remainder 165, and apply the division lemma to get
207 = 165 x 1 + 42
We consider the new divisor 165 and the new remainder 42,and apply the division lemma to get
165 = 42 x 3 + 39
We consider the new divisor 42 and the new remainder 39,and apply the division lemma to get
42 = 39 x 1 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 579 and 786 is 3
Notice that 3 = HCF(39,3) = HCF(42,39) = HCF(165,42) = HCF(207,165) = HCF(579,207) = HCF(786,579) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 831 > 3, we apply the division lemma to 831 and 3, to get
831 = 3 x 277 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 831 is 3
Notice that 3 = HCF(831,3) .
