HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 663 i.e. 39 the largest integer that leaves a remainder zero for all numbers.
HCF of 195, 663 is 39 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 195, 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 195, 663 is 39.
HCF(195, 663) = 39
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 195, 663 is 39.
Step 1: Since 663 > 195, we apply the division lemma to 663 and 195, to get
663 = 195 x 3 + 78
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 78 and 195, to get
195 = 78 x 2 + 39
Step 3: We consider the new divisor 78 and the new remainder 39, and apply the division lemma to get
78 = 39 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 195 and 663 is 39
Notice that 39 = HCF(78,39) = HCF(195,78) = HCF(663,195) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 195, 663?
Answer: HCF of 195, 663 is 39 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 195, 663 using Euclid's Algorithm?
Answer: For arbitrary numbers 195, 663 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
