HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 725, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 725, 949 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 725, 949 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 725, 949 is 1.
HCF(725, 949) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 725, 949 is 1.
Step 1: Since 949 > 725, we apply the division lemma to 949 and 725, to get
949 = 725 x 1 + 224
Step 2: Since the reminder 725 ≠ 0, we apply division lemma to 224 and 725, to get
725 = 224 x 3 + 53
Step 3: We consider the new divisor 224 and the new remainder 53, and apply the division lemma to get
224 = 53 x 4 + 12
We consider the new divisor 53 and the new remainder 12,and apply the division lemma to get
53 = 12 x 4 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 725 and 949 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(53,12) = HCF(224,53) = HCF(725,224) = HCF(949,725) .
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 725, 949?
Answer: HCF of 725, 949 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 725, 949 using Euclid's Algorithm?
Answer: For arbitrary numbers 725, 949 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
