HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 860, 131, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 860, 131, 31 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 231, 860, 131, 31 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 231, 860, 131, 31 is 1.
HCF(231, 860, 131, 31) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 860, 131, 31 is 1.
Step 1: Since 860 > 231, we apply the division lemma to 860 and 231, to get
860 = 231 x 3 + 167
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 167 and 231, to get
231 = 167 x 1 + 64
Step 3: We consider the new divisor 167 and the new remainder 64, and apply the division lemma to get
167 = 64 x 2 + 39
We consider the new divisor 64 and the new remainder 39,and apply the division lemma to get
64 = 39 x 1 + 25
We consider the new divisor 39 and the new remainder 25,and apply the division lemma to get
39 = 25 x 1 + 14
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 231 and 860 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(64,39) = HCF(167,64) = HCF(231,167) = HCF(860,231) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 131 > 1, we apply the division lemma to 131 and 1, to get
131 = 1 x 131 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 131 is 1
Notice that 1 = HCF(131,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 1, we apply the division lemma to 31 and 1, to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31 is 1
Notice that 1 = HCF(31,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
