HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 697 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 404, 697 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 404, 697 is 1.
HCF(404, 697) = 1
HCF of 404, 697 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 697 is 1.
Highest Common Factor of 404,697 is 1
Step 1: Since 697 > 404, we apply the division lemma to 697 and 404, to get
697 = 404 x 1 + 293
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 293 and 404, to get
404 = 293 x 1 + 111
Step 3: We consider the new divisor 293 and the new remainder 111, and apply the division lemma to get
293 = 111 x 2 + 71
We consider the new divisor 111 and the new remainder 71,and apply the division lemma to get
111 = 71 x 1 + 40
We consider the new divisor 71 and the new remainder 40,and apply the division lemma to get
71 = 40 x 1 + 31
We consider the new divisor 40 and the new remainder 31,and apply the division lemma to get
40 = 31 x 1 + 9
We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get
31 = 9 x 3 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 404 and 697 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(40,31) = HCF(71,40) = HCF(111,71) = HCF(293,111) = HCF(404,293) = HCF(697,404) .
