HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 697, 663 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 697, 663 is 17 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 697, 663 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 697, 663 is 17.
HCF(697, 663) = 17
HCF of 697, 663 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 697, 663 is 17.
Highest Common Factor of 697,663 is 17
Step 1: Since 697 > 663, we apply the division lemma to 697 and 663, to get
697 = 663 x 1 + 34
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 34 and 663, to get
663 = 34 x 19 + 17
Step 3: We consider the new divisor 34 and the new remainder 17, and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 697 and 663 is 17
Notice that 17 = HCF(34,17) = HCF(663,34) = HCF(697,663) .
