HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 809, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 150, 809, 243 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 150, 809, 243 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 150, 809, 243 is 1.
HCF(150, 809, 243) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 150, 809, 243 is 1.
Step 1: Since 809 > 150, we apply the division lemma to 809 and 150, to get
809 = 150 x 5 + 59
Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 59 and 150, to get
150 = 59 x 2 + 32
Step 3: We consider the new divisor 59 and the new remainder 32, and apply the division lemma to get
59 = 32 x 1 + 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 150 and 809 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(32,27) = HCF(59,32) = HCF(150,59) = HCF(809,150) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 243 > 1, we apply the division lemma to 243 and 1, to get
243 = 1 x 243 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 243 is 1
Notice that 1 = HCF(243,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 150, 809, 243?
Answer: HCF of 150, 809, 243 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 150, 809, 243 using Euclid's Algorithm?
Answer: For arbitrary numbers 150, 809, 243 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
