HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 293 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 293 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 693, 293 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 693, 293 is 1.
HCF(693, 293) = 1
HCF of 693, 293 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 293 is 1.
Highest Common Factor of 693,293 is 1
Step 1: Since 693 > 293, we apply the division lemma to 693 and 293, to get
693 = 293 x 2 + 107
Step 2: Since the reminder 293 ≠ 0, we apply division lemma to 107 and 293, to get
293 = 107 x 2 + 79
Step 3: We consider the new divisor 107 and the new remainder 79, and apply the division lemma to get
107 = 79 x 1 + 28
We consider the new divisor 79 and the new remainder 28,and apply the division lemma to get
79 = 28 x 2 + 23
We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 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 693 and 293 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(79,28) = HCF(107,79) = HCF(293,107) = HCF(693,293) .
