HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 200, 404 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 643, 200, 404 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 643, 200, 404 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 643, 200, 404 is 1.
HCF(643, 200, 404) = 1
HCF of 643, 200, 404 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 643, 200, 404 is 1.
Highest Common Factor of 643,200,404 is 1
Step 1: Since 643 > 200, we apply the division lemma to 643 and 200, to get
643 = 200 x 3 + 43
Step 2: Since the reminder 200 ≠ 0, we apply division lemma to 43 and 200, to get
200 = 43 x 4 + 28
Step 3: We consider the new divisor 43 and the new remainder 28, and apply the division lemma to get
43 = 28 x 1 + 15
We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get
28 = 15 x 1 + 13
We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get
15 = 13 x 1 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 643 and 200 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(43,28) = HCF(200,43) = HCF(643,200) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 404 > 1, we apply the division lemma to 404 and 1, to get
404 = 1 x 404 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 404 is 1
Notice that 1 = HCF(404,1) .
