HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 254, 991, 633 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 254, 991, 633 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 254, 991, 633 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 254, 991, 633 is 1.
HCF(254, 991, 633) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 254, 991, 633 is 1.
Step 1: Since 991 > 254, we apply the division lemma to 991 and 254, to get
991 = 254 x 3 + 229
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 229 and 254, to get
254 = 229 x 1 + 25
Step 3: We consider the new divisor 229 and the new remainder 25, and apply the division lemma to get
229 = 25 x 9 + 4
We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 254 and 991 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(229,25) = HCF(254,229) = HCF(991,254) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 633 > 1, we apply the division lemma to 633 and 1, to get
633 = 1 x 633 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 633 is 1
Notice that 1 = HCF(633,1) .
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 254, 991, 633?
Answer: HCF of 254, 991, 633 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 254, 991, 633 using Euclid's Algorithm?
Answer: For arbitrary numbers 254, 991, 633 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
