HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 322, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 322, 393 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 322, 393 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 322, 393 is 1.
HCF(322, 393) = 1
HCF of 322, 393 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 322, 393 is 1.
Highest Common Factor of 322,393 is 1
Step 1: Since 393 > 322, we apply the division lemma to 393 and 322, to get
393 = 322 x 1 + 71
Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 71 and 322, to get
322 = 71 x 4 + 38
Step 3: We consider the new divisor 71 and the new remainder 38, and apply the division lemma to get
71 = 38 x 1 + 33
We consider the new divisor 38 and the new remainder 33,and apply the division lemma to get
38 = 33 x 1 + 5
We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get
33 = 5 x 6 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 322 and 393 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(38,33) = HCF(71,38) = HCF(322,71) = HCF(393,322) .
