HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 769, 901 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 769, 901 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 998, 769, 901 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 998, 769, 901 is 1.
HCF(998, 769, 901) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 998, 769, 901 is 1.
Step 1: Since 998 > 769, we apply the division lemma to 998 and 769, to get
998 = 769 x 1 + 229
Step 2: Since the reminder 769 ≠ 0, we apply division lemma to 229 and 769, to get
769 = 229 x 3 + 82
Step 3: We consider the new divisor 229 and the new remainder 82, and apply the division lemma to get
229 = 82 x 2 + 65
We consider the new divisor 82 and the new remainder 65,and apply the division lemma to get
82 = 65 x 1 + 17
We consider the new divisor 65 and the new remainder 17,and apply the division lemma to get
65 = 17 x 3 + 14
We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get
17 = 14 x 1 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 998 and 769 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(65,17) = HCF(82,65) = HCF(229,82) = HCF(769,229) = HCF(998,769) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 901 > 1, we apply the division lemma to 901 and 1, to get
901 = 1 x 901 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 901 is 1
Notice that 1 = HCF(901,1) .
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 998, 769, 901?
Answer: HCF of 998, 769, 901 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 998, 769, 901 using Euclid's Algorithm?
Answer: For arbitrary numbers 998, 769, 901 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
