HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 695, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 695, 997 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 695, 997 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 695, 997 is 1.
HCF(695, 997) = 1
HCF of 695, 997 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 695, 997 is 1.
Highest Common Factor of 695,997 is 1
Step 1: Since 997 > 695, we apply the division lemma to 997 and 695, to get
997 = 695 x 1 + 302
Step 2: Since the reminder 695 ≠ 0, we apply division lemma to 302 and 695, to get
695 = 302 x 2 + 91
Step 3: We consider the new divisor 302 and the new remainder 91, and apply the division lemma to get
302 = 91 x 3 + 29
We consider the new divisor 91 and the new remainder 29,and apply the division lemma to get
91 = 29 x 3 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 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 695 and 997 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(91,29) = HCF(302,91) = HCF(695,302) = HCF(997,695) .
