HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 613, 400 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 745, 613, 400 is 1 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 745, 613, 400 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 745, 613, 400 is 1.
HCF(745, 613, 400) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 745, 613, 400 is 1.
Step 1: Since 745 > 613, we apply the division lemma to 745 and 613, to get
745 = 613 x 1 + 132
Step 2: Since the reminder 613 ≠ 0, we apply division lemma to 132 and 613, to get
613 = 132 x 4 + 85
Step 3: We consider the new divisor 132 and the new remainder 85, and apply the division lemma to get
132 = 85 x 1 + 47
We consider the new divisor 85 and the new remainder 47,and apply the division lemma to get
85 = 47 x 1 + 38
We consider the new divisor 47 and the new remainder 38,and apply the division lemma to get
47 = 38 x 1 + 9
We consider the new divisor 38 and the new remainder 9,and apply the division lemma to get
38 = 9 x 4 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 745 and 613 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(38,9) = HCF(47,38) = HCF(85,47) = HCF(132,85) = HCF(613,132) = HCF(745,613) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 400 > 1, we apply the division lemma to 400 and 1, to get
400 = 1 x 400 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 400 is 1
Notice that 1 = HCF(400,1) .
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 745, 613, 400?
Answer: HCF of 745, 613, 400 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 745, 613, 400 using Euclid's Algorithm?
Answer: For arbitrary numbers 745, 613, 400 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
