HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 735, 309, 843 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 735, 309, 843 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 735, 309, 843 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 735, 309, 843 is 3.
HCF(735, 309, 843) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 735, 309, 843 is 3.
Step 1: Since 735 > 309, we apply the division lemma to 735 and 309, to get
735 = 309 x 2 + 117
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 117 and 309, to get
309 = 117 x 2 + 75
Step 3: We consider the new divisor 117 and the new remainder 75, and apply the division lemma to get
117 = 75 x 1 + 42
We consider the new divisor 75 and the new remainder 42,and apply the division lemma to get
75 = 42 x 1 + 33
We consider the new divisor 42 and the new remainder 33,and apply the division lemma to get
42 = 33 x 1 + 9
We consider the new divisor 33 and the new remainder 9,and apply the division lemma to get
33 = 9 x 3 + 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 735 and 309 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(33,9) = HCF(42,33) = HCF(75,42) = HCF(117,75) = HCF(309,117) = HCF(735,309) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 843 > 3, we apply the division lemma to 843 and 3, to get
843 = 3 x 281 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 843 is 3
Notice that 3 = HCF(843,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
