HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 7001, 9368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 7001, 9368 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, 7001, 9368 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, 7001, 9368 is 1.
HCF(393, 7001, 9368) = 1
HCF of 393, 7001, 9368 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, 7001, 9368 is 1.
Highest Common Factor of 393,7001,9368 is 1
Step 1: Since 7001 > 393, we apply the division lemma to 7001 and 393, to get
7001 = 393 x 17 + 320
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 320 and 393, to get
393 = 320 x 1 + 73
Step 3: We consider the new divisor 320 and the new remainder 73, and apply the division lemma to get
320 = 73 x 4 + 28
We consider the new divisor 73 and the new remainder 28,and apply the division lemma to get
73 = 28 x 2 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 393 and 7001 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(73,28) = HCF(320,73) = HCF(393,320) = HCF(7001,393) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9368 > 1, we apply the division lemma to 9368 and 1, to get
9368 = 1 x 9368 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 9368 is 1
Notice that 1 = HCF(9368,1) .
