HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 735, 618 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 735, 618 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 462, 735, 618 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 462, 735, 618 is 3.
HCF(462, 735, 618) = 3
HCF of 462, 735, 618 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 735, 618 is 3.
Highest Common Factor of 462,735,618 is 3
Step 1: Since 735 > 462, we apply the division lemma to 735 and 462, to get
735 = 462 x 1 + 273
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 273 and 462, to get
462 = 273 x 1 + 189
Step 3: We consider the new divisor 273 and the new remainder 189, and apply the division lemma to get
273 = 189 x 1 + 84
We consider the new divisor 189 and the new remainder 84,and apply the division lemma to get
189 = 84 x 2 + 21
We consider the new divisor 84 and the new remainder 21,and apply the division lemma to get
84 = 21 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 462 and 735 is 21
Notice that 21 = HCF(84,21) = HCF(189,84) = HCF(273,189) = HCF(462,273) = HCF(735,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 618 > 21, we apply the division lemma to 618 and 21, to get
618 = 21 x 29 + 9
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 9 and 21, to get
21 = 9 x 2 + 3
Step 3: We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 21 and 618 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(618,21) .
