HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 384, 830 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 384, 830 is 1 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 609, 384, 830 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 609, 384, 830 is 1.
HCF(609, 384, 830) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 384, 830 is 1.
Step 1: Since 609 > 384, we apply the division lemma to 609 and 384, to get
609 = 384 x 1 + 225
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 225 and 384, to get
384 = 225 x 1 + 159
Step 3: We consider the new divisor 225 and the new remainder 159, and apply the division lemma to get
225 = 159 x 1 + 66
We consider the new divisor 159 and the new remainder 66,and apply the division lemma to get
159 = 66 x 2 + 27
We consider the new divisor 66 and the new remainder 27,and apply the division lemma to get
66 = 27 x 2 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 609 and 384 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(66,27) = HCF(159,66) = HCF(225,159) = HCF(384,225) = HCF(609,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 830 > 3, we apply the division lemma to 830 and 3, to get
830 = 3 x 276 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 830 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(830,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
