HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 201, 731, 286, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 201, 731, 286, 54 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, 731, 286, 54 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, 731, 286, 54 is 1.
HCF(201, 731, 286, 54) = 1
HCF of 201, 731, 286, 54 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, 731, 286, 54 is 1.
Highest Common Factor of 201,731,286,54 is 1
Step 1: Since 731 > 201, we apply the division lemma to 731 and 201, to get
731 = 201 x 3 + 128
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 128 and 201, to get
201 = 128 x 1 + 73
Step 3: We consider the new divisor 128 and the new remainder 73, and apply the division lemma to get
128 = 73 x 1 + 55
We consider the new divisor 73 and the new remainder 55,and apply the division lemma to get
73 = 55 x 1 + 18
We consider the new divisor 55 and the new remainder 18,and apply the division lemma to get
55 = 18 x 3 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 201 and 731 is 1
Notice that 1 = HCF(18,1) = HCF(55,18) = HCF(73,55) = HCF(128,73) = HCF(201,128) = HCF(731,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 286 > 1, we apply the division lemma to 286 and 1, to get
286 = 1 x 286 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 286 is 1
Notice that 1 = HCF(286,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
