HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 221, 201, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 12, 221, 201, 712 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 12, 221, 201, 712 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 12, 221, 201, 712 is 1.
HCF(12, 221, 201, 712) = 1
HCF of 12, 221, 201, 712 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 12, 221, 201, 712 is 1.
Highest Common Factor of 12,221,201,712 is 1
Step 1: Since 221 > 12, we apply the division lemma to 221 and 12, to get
221 = 12 x 18 + 5
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 5 and 12, to get
12 = 5 x 2 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 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 12 and 221 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(221,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 201 > 1, we apply the division lemma to 201 and 1, to get
201 = 1 x 201 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 201 is 1
Notice that 1 = HCF(201,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 712 > 1, we apply the division lemma to 712 and 1, to get
712 = 1 x 712 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 712 is 1
Notice that 1 = HCF(712,1) .
