HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 201, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 201, 451 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 201, 451 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 201, 451 is 1.
HCF(201, 451) = 1
HCF of 201, 451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 201, 451 is 1.
Highest Common Factor of 201,451 is 1
Step 1: Since 451 > 201, we apply the division lemma to 451 and 201, to get
451 = 201 x 2 + 49
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 49 and 201, to get
201 = 49 x 4 + 5
Step 3: We consider the new divisor 49 and the new remainder 5, and apply the division lemma to get
49 = 5 x 9 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 201 and 451 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(49,5) = HCF(201,49) = HCF(451,201) .
