HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 451, 637, 796 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 451, 637, 796 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 451, 637, 796 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 451, 637, 796 is 1.
HCF(451, 637, 796) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 451, 637, 796 is 1.
Step 1: Since 637 > 451, we apply the division lemma to 637 and 451, to get
637 = 451 x 1 + 186
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 186 and 451, to get
451 = 186 x 2 + 79
Step 3: We consider the new divisor 186 and the new remainder 79, and apply the division lemma to get
186 = 79 x 2 + 28
We consider the new divisor 79 and the new remainder 28,and apply the division lemma to get
79 = 28 x 2 + 23
We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 451 and 637 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(79,28) = HCF(186,79) = HCF(451,186) = HCF(637,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 796 > 1, we apply the division lemma to 796 and 1, to get
796 = 1 x 796 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 796 is 1
Notice that 1 = HCF(796,1) .
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 451, 637, 796?
Answer: HCF of 451, 637, 796 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 451, 637, 796 using Euclid's Algorithm?
