HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 658, 450 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 475, 658, 450 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 475, 658, 450 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 475, 658, 450 is 1.
HCF(475, 658, 450) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 475, 658, 450 is 1.
Step 1: Since 658 > 475, we apply the division lemma to 658 and 475, to get
658 = 475 x 1 + 183
Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 183 and 475, to get
475 = 183 x 2 + 109
Step 3: We consider the new divisor 183 and the new remainder 109, and apply the division lemma to get
183 = 109 x 1 + 74
We consider the new divisor 109 and the new remainder 74,and apply the division lemma to get
109 = 74 x 1 + 35
We consider the new divisor 74 and the new remainder 35,and apply the division lemma to get
74 = 35 x 2 + 4
We consider the new divisor 35 and the new remainder 4,and apply the division lemma to get
35 = 4 x 8 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 475 and 658 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(35,4) = HCF(74,35) = HCF(109,74) = HCF(183,109) = HCF(475,183) = HCF(658,475) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 450 > 1, we apply the division lemma to 450 and 1, to get
450 = 1 x 450 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 450 is 1
Notice that 1 = HCF(450,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 475, 658, 450?
Answer: HCF of 475, 658, 450 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 475, 658, 450 using Euclid's Algorithm?
Answer: For arbitrary numbers 475, 658, 450 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
