HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 201, 474, 939 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 201, 474, 939 is 3 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, 474, 939 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, 474, 939 is 3.
HCF(201, 474, 939) = 3
HCF of 201, 474, 939 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, 474, 939 is 3.
Highest Common Factor of 201,474,939 is 3
Step 1: Since 474 > 201, we apply the division lemma to 474 and 201, to get
474 = 201 x 2 + 72
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 72 and 201, to get
201 = 72 x 2 + 57
Step 3: We consider the new divisor 72 and the new remainder 57, and apply the division lemma to get
72 = 57 x 1 + 15
We consider the new divisor 57 and the new remainder 15,and apply the division lemma to get
57 = 15 x 3 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 201 and 474 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(57,15) = HCF(72,57) = HCF(201,72) = HCF(474,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 939 > 3, we apply the division lemma to 939 and 3, to get
939 = 3 x 313 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 939 is 3
Notice that 3 = HCF(939,3) .
