HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 3452, 720 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 3452, 720 is 4 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 3452, 720 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 3452, 720 is 4.
HCF(3452, 720) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 3452, 720 is 4.
Step 1: Since 3452 > 720, we apply the division lemma to 3452 and 720, to get
3452 = 720 x 4 + 572
Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 572 and 720, to get
720 = 572 x 1 + 148
Step 3: We consider the new divisor 572 and the new remainder 148, and apply the division lemma to get
572 = 148 x 3 + 128
We consider the new divisor 148 and the new remainder 128,and apply the division lemma to get
148 = 128 x 1 + 20
We consider the new divisor 128 and the new remainder 20,and apply the division lemma to get
128 = 20 x 6 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 3452 and 720 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(128,20) = HCF(148,128) = HCF(572,148) = HCF(720,572) = HCF(3452,720) .
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 3452, 720?
Answer: HCF of 3452, 720 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 3452, 720 using Euclid's Algorithm?
Answer: For arbitrary numbers 3452, 720 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
