HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 743 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, 743 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, 743 is 1.
HCF(663, 743) = 1
HCF of 663, 743 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, 743 is 1.
Highest Common Factor of 663,743 is 1
Step 1: Since 743 > 663, we apply the division lemma to 743 and 663, to get
743 = 663 x 1 + 80
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 80 and 663, to get
663 = 80 x 8 + 23
Step 3: We consider the new divisor 80 and the new remainder 23, and apply the division lemma to get
80 = 23 x 3 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 663 and 743 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(80,23) = HCF(663,80) = HCF(743,663) .
