HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 923 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 923 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 393, 923 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 393, 923 is 1.
HCF(393, 923) = 1
HCF of 393, 923 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 393, 923 is 1.
Highest Common Factor of 393,923 is 1
Step 1: Since 923 > 393, we apply the division lemma to 923 and 393, to get
923 = 393 x 2 + 137
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 137 and 393, to get
393 = 137 x 2 + 119
Step 3: We consider the new divisor 137 and the new remainder 119, and apply the division lemma to get
137 = 119 x 1 + 18
We consider the new divisor 119 and the new remainder 18,and apply the division lemma to get
119 = 18 x 6 + 11
We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get
18 = 11 x 1 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 393 and 923 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(119,18) = HCF(137,119) = HCF(393,137) = HCF(923,393) .
