HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 246, 471, 855, 687 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 246, 471, 855, 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 246, 471, 855, 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 246, 471, 855, 687 is 3.
HCF(246, 471, 855, 687) = 3
HCF of 246, 471, 855, 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 246, 471, 855, 687 is 3.
Highest Common Factor of 246,471,855,687 is 3
Step 1: Since 471 > 246, we apply the division lemma to 471 and 246, to get
471 = 246 x 1 + 225
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 225 and 246, to get
246 = 225 x 1 + 21
Step 3: We consider the new divisor 225 and the new remainder 21, and apply the division lemma to get
225 = 21 x 10 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 246 and 471 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(225,21) = HCF(246,225) = HCF(471,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 3, we apply the division lemma to 855 and 3, to get
855 = 3 x 285 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 855 is 3
Notice that 3 = HCF(855,3) .
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) .
