HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 908, 109 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 908, 109 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 801, 908, 109 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 801, 908, 109 is 1.
HCF(801, 908, 109) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 908, 109 is 1.
Step 1: Since 908 > 801, we apply the division lemma to 908 and 801, to get
908 = 801 x 1 + 107
Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 107 and 801, to get
801 = 107 x 7 + 52
Step 3: We consider the new divisor 107 and the new remainder 52, and apply the division lemma to get
107 = 52 x 2 + 3
We consider the new divisor 52 and the new remainder 3,and apply the division lemma to get
52 = 3 x 17 + 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 801 and 908 is 1
Notice that 1 = HCF(3,1) = HCF(52,3) = HCF(107,52) = HCF(801,107) = HCF(908,801) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 109 > 1, we apply the division lemma to 109 and 1, to get
109 = 1 x 109 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 109 is 1
Notice that 1 = HCF(109,1) .
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 801, 908, 109?
Answer: HCF of 801, 908, 109 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 801, 908, 109 using Euclid's Algorithm?
Answer: For arbitrary numbers 801, 908, 109 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
