HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 393, 706 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 393, 706 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 309, 393, 706 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 309, 393, 706 is 1.
HCF(309, 393, 706) = 1
HCF of 309, 393, 706 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 393, 706 is 1.
Highest Common Factor of 309,393,706 is 1
Step 1: Since 393 > 309, we apply the division lemma to 393 and 309, to get
393 = 309 x 1 + 84
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 84 and 309, to get
309 = 84 x 3 + 57
Step 3: We consider the new divisor 84 and the new remainder 57, and apply the division lemma to get
84 = 57 x 1 + 27
We consider the new divisor 57 and the new remainder 27,and apply the division lemma to get
57 = 27 x 2 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 309 and 393 is 3
Notice that 3 = HCF(27,3) = HCF(57,27) = HCF(84,57) = HCF(309,84) = HCF(393,309) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 3, we apply the division lemma to 706 and 3, to get
706 = 3 x 235 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 706 is 1
Notice that 1 = HCF(3,1) = HCF(706,3) .
