HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 755, 7149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 755, 7149 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 755, 7149 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 755, 7149 is 1.
HCF(755, 7149) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 755, 7149 is 1.
Step 1: Since 7149 > 755, we apply the division lemma to 7149 and 755, to get
7149 = 755 x 9 + 354
Step 2: Since the reminder 755 ≠ 0, we apply division lemma to 354 and 755, to get
755 = 354 x 2 + 47
Step 3: We consider the new divisor 354 and the new remainder 47, and apply the division lemma to get
354 = 47 x 7 + 25
We consider the new divisor 47 and the new remainder 25,and apply the division lemma to get
47 = 25 x 1 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 755 and 7149 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(47,25) = HCF(354,47) = HCF(755,354) = HCF(7149,755) .
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 755, 7149?
Answer: HCF of 755, 7149 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 755, 7149 using Euclid's Algorithm?
Answer: For arbitrary numbers 755, 7149 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
