HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 867, 18 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 867, 18 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 459, 867, 18 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 459, 867, 18 is 3.
HCF(459, 867, 18) = 3
HCF of 459, 867, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 867, 18 is 3.
Highest Common Factor of 459,867,18 is 3
Step 1: Since 867 > 459, we apply the division lemma to 867 and 459, to get
867 = 459 x 1 + 408
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 408 and 459, to get
459 = 408 x 1 + 51
Step 3: We consider the new divisor 408 and the new remainder 51, and apply the division lemma to get
408 = 51 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 459 and 867 is 51
Notice that 51 = HCF(408,51) = HCF(459,408) = HCF(867,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 18, we apply the division lemma to 51 and 18, to get
51 = 18 x 2 + 15
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 15 and 18, to get
18 = 15 x 1 + 3
Step 3: We consider the new divisor 15 and the new remainder 3, and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 51 and 18 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(51,18) .
