HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 663 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 663 is 3 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 393, 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 393, 663 is 3.
HCF(393, 663) = 3
HCF of 393, 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 393, 663 is 3.
Highest Common Factor of 393,663 is 3
Step 1: Since 663 > 393, we apply the division lemma to 663 and 393, to get
663 = 393 x 1 + 270
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 270 and 393, to get
393 = 270 x 1 + 123
Step 3: We consider the new divisor 270 and the new remainder 123, and apply the division lemma to get
270 = 123 x 2 + 24
We consider the new divisor 123 and the new remainder 24,and apply the division lemma to get
123 = 24 x 5 + 3
We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 393 and 663 is 3
Notice that 3 = HCF(24,3) = HCF(123,24) = HCF(270,123) = HCF(393,270) = HCF(663,393) .
