HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 9683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 9683 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 663, 9683 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 663, 9683 is 1.
HCF(663, 9683) = 1
HCF of 663, 9683 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 663, 9683 is 1.
Highest Common Factor of 663,9683 is 1
Step 1: Since 9683 > 663, we apply the division lemma to 9683 and 663, to get
9683 = 663 x 14 + 401
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 401 and 663, to get
663 = 401 x 1 + 262
Step 3: We consider the new divisor 401 and the new remainder 262, and apply the division lemma to get
401 = 262 x 1 + 139
We consider the new divisor 262 and the new remainder 139,and apply the division lemma to get
262 = 139 x 1 + 123
We consider the new divisor 139 and the new remainder 123,and apply the division lemma to get
139 = 123 x 1 + 16
We consider the new divisor 123 and the new remainder 16,and apply the division lemma to get
123 = 16 x 7 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 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 663 and 9683 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(123,16) = HCF(139,123) = HCF(262,139) = HCF(401,262) = HCF(663,401) = HCF(9683,663) .
