HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 702, 81 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 702, 81 is 27 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 702, 81 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 702, 81 is 27.
HCF(702, 81) = 27
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 702, 81 is 27.
Step 1: Since 702 > 81, we apply the division lemma to 702 and 81, to get
702 = 81 x 8 + 54
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 54 and 81, to get
81 = 54 x 1 + 27
Step 3: We consider the new divisor 54 and the new remainder 27, and apply the division lemma to get
54 = 27 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 702 and 81 is 27
Notice that 27 = HCF(54,27) = HCF(81,54) = HCF(702,81) .
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 702, 81?
Answer: HCF of 702, 81 is 27 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 702, 81 using Euclid's Algorithm?
Answer: For arbitrary numbers 702, 81 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
