HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 406 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 625, 406 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 625, 406 is 1.
HCF(625, 406) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 406 is 1.
Step 1: Since 625 > 406, we apply the division lemma to 625 and 406, to get
625 = 406 x 1 + 219
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 219 and 406, to get
406 = 219 x 1 + 187
Step 3: We consider the new divisor 219 and the new remainder 187, and apply the division lemma to get
219 = 187 x 1 + 32
We consider the new divisor 187 and the new remainder 32,and apply the division lemma to get
187 = 32 x 5 + 27
We consider the new divisor 32 and the new remainder 27,and apply the division lemma to get
32 = 27 x 1 + 5
We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get
27 = 5 x 5 + 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 625 and 406 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(32,27) = HCF(187,32) = HCF(219,187) = HCF(406,219) = HCF(625,406) .
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 625, 406?
Answer: HCF of 625, 406 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 625, 406 using Euclid's Algorithm?
Answer: For arbitrary numbers 625, 406 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
