HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 702 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 702 is 2 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 820, 702 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 820, 702 is 2.
HCF(820, 702) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 702 is 2.
Step 1: Since 820 > 702, we apply the division lemma to 820 and 702, to get
820 = 702 x 1 + 118
Step 2: Since the reminder 702 ≠ 0, we apply division lemma to 118 and 702, to get
702 = 118 x 5 + 112
Step 3: We consider the new divisor 118 and the new remainder 112, and apply the division lemma to get
118 = 112 x 1 + 6
We consider the new divisor 112 and the new remainder 6,and apply the division lemma to get
112 = 6 x 18 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 820 and 702 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(112,6) = HCF(118,112) = HCF(702,118) = HCF(820,702) .
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 820, 702?
Answer: HCF of 820, 702 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 820, 702 using Euclid's Algorithm?
Answer: For arbitrary numbers 820, 702 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
