HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 201, 945, 828 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 201, 945, 828 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, 945, 828 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, 945, 828 is 3.
HCF(201, 945, 828) = 3
HCF of 201, 945, 828 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, 945, 828 is 3.
Highest Common Factor of 201,945,828 is 3
Step 1: Since 945 > 201, we apply the division lemma to 945 and 201, to get
945 = 201 x 4 + 141
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 141 and 201, to get
201 = 141 x 1 + 60
Step 3: We consider the new divisor 141 and the new remainder 60, and apply the division lemma to get
141 = 60 x 2 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 201 and 945 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(141,60) = HCF(201,141) = HCF(945,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 828 > 3, we apply the division lemma to 828 and 3, to get
828 = 3 x 276 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 828 is 3
Notice that 3 = HCF(828,3) .
