HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 727, 39, 218, 352 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 727, 39, 218, 352 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 727, 39, 218, 352 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 727, 39, 218, 352 is 1.
HCF(727, 39, 218, 352) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 727, 39, 218, 352 is 1.
Step 1: Since 727 > 39, we apply the division lemma to 727 and 39, to get
727 = 39 x 18 + 25
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 25 and 39, to get
39 = 25 x 1 + 14
Step 3: We consider the new divisor 25 and the new remainder 14, and apply the division lemma to get
25 = 14 x 1 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 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 727 and 39 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(727,39) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 218 > 1, we apply the division lemma to 218 and 1, to get
218 = 1 x 218 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 218 is 1
Notice that 1 = HCF(218,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 352 > 1, we apply the division lemma to 352 and 1, to get
352 = 1 x 352 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 352 is 1
Notice that 1 = HCF(352,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
