HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 604, 921 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 604, 921 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 604, 921 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 604, 921 is 1.
HCF(604, 921) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 604, 921 is 1.
Step 1: Since 921 > 604, we apply the division lemma to 921 and 604, to get
921 = 604 x 1 + 317
Step 2: Since the reminder 604 ≠ 0, we apply division lemma to 317 and 604, to get
604 = 317 x 1 + 287
Step 3: We consider the new divisor 317 and the new remainder 287, and apply the division lemma to get
317 = 287 x 1 + 30
We consider the new divisor 287 and the new remainder 30,and apply the division lemma to get
287 = 30 x 9 + 17
We consider the new divisor 30 and the new remainder 17,and apply the division lemma to get
30 = 17 x 1 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 604 and 921 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(30,17) = HCF(287,30) = HCF(317,287) = HCF(604,317) = HCF(921,604) .
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 604, 921?
Answer: HCF of 604, 921 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 604, 921 using Euclid's Algorithm?
Answer: For arbitrary numbers 604, 921 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
