HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 474, 801, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 474, 801, 905 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 474, 801, 905 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 474, 801, 905 is 1.
HCF(474, 801, 905) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 474, 801, 905 is 1.
Step 1: Since 801 > 474, we apply the division lemma to 801 and 474, to get
801 = 474 x 1 + 327
Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 327 and 474, to get
474 = 327 x 1 + 147
Step 3: We consider the new divisor 327 and the new remainder 147, and apply the division lemma to get
327 = 147 x 2 + 33
We consider the new divisor 147 and the new remainder 33,and apply the division lemma to get
147 = 33 x 4 + 15
We consider the new divisor 33 and the new remainder 15,and apply the division lemma to get
33 = 15 x 2 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 474 and 801 is 3
Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(147,33) = HCF(327,147) = HCF(474,327) = HCF(801,474) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 905 > 3, we apply the division lemma to 905 and 3, to get
905 = 3 x 301 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 905 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(905,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 474, 801, 905?
Answer: HCF of 474, 801, 905 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 474, 801, 905 using Euclid's Algorithm?
Answer: For arbitrary numbers 474, 801, 905 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
