HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 969, 306 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 969, 306 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 618, 969, 306 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 618, 969, 306 is 3.
HCF(618, 969, 306) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 969, 306 is 3.
Step 1: Since 969 > 618, we apply the division lemma to 969 and 618, to get
969 = 618 x 1 + 351
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 351 and 618, to get
618 = 351 x 1 + 267
Step 3: We consider the new divisor 351 and the new remainder 267, and apply the division lemma to get
351 = 267 x 1 + 84
We consider the new divisor 267 and the new remainder 84,and apply the division lemma to get
267 = 84 x 3 + 15
We consider the new divisor 84 and the new remainder 15,and apply the division lemma to get
84 = 15 x 5 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 618 and 969 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(84,15) = HCF(267,84) = HCF(351,267) = HCF(618,351) = HCF(969,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 3, we apply the division lemma to 306 and 3, to get
306 = 3 x 102 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 306 is 3
Notice that 3 = HCF(306,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
