HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 997, 409, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 872, 997, 409, 393 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 872, 997, 409, 393 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 872, 997, 409, 393 is 1.
HCF(872, 997, 409, 393) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 872, 997, 409, 393 is 1.
Step 1: Since 997 > 872, we apply the division lemma to 997 and 872, to get
997 = 872 x 1 + 125
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 125 and 872, to get
872 = 125 x 6 + 122
Step 3: We consider the new divisor 125 and the new remainder 122, and apply the division lemma to get
125 = 122 x 1 + 3
We consider the new divisor 122 and the new remainder 3,and apply the division lemma to get
122 = 3 x 40 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 872 and 997 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(122,3) = HCF(125,122) = HCF(872,125) = HCF(997,872) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 409 > 1, we apply the division lemma to 409 and 1, to get
409 = 1 x 409 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 409 is 1
Notice that 1 = HCF(409,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get
393 = 1 x 393 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1
Notice that 1 = HCF(393,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
