HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 523, 891, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 523, 891, 475 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 523, 891, 475 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 523, 891, 475 is 1.
HCF(523, 891, 475) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 523, 891, 475 is 1.
Step 1: Since 891 > 523, we apply the division lemma to 891 and 523, to get
891 = 523 x 1 + 368
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 368 and 523, to get
523 = 368 x 1 + 155
Step 3: We consider the new divisor 368 and the new remainder 155, and apply the division lemma to get
368 = 155 x 2 + 58
We consider the new divisor 155 and the new remainder 58,and apply the division lemma to get
155 = 58 x 2 + 39
We consider the new divisor 58 and the new remainder 39,and apply the division lemma to get
58 = 39 x 1 + 19
We consider the new divisor 39 and the new remainder 19,and apply the division lemma to get
39 = 19 x 2 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 523 and 891 is 1
Notice that 1 = HCF(19,1) = HCF(39,19) = HCF(58,39) = HCF(155,58) = HCF(368,155) = HCF(523,368) = HCF(891,523) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get
475 = 1 x 475 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1
Notice that 1 = HCF(475,1) .
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 523, 891, 475?
Answer: HCF of 523, 891, 475 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 523, 891, 475 using Euclid's Algorithm?
Answer: For arbitrary numbers 523, 891, 475 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
