HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2231, 3151 i.e. 23 the largest integer that leaves a remainder zero for all numbers.
HCF of 2231, 3151 is 23 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 2231, 3151 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 2231, 3151 is 23.
HCF(2231, 3151) = 23
HCF of 2231, 3151 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2231, 3151 is 23.
Highest Common Factor of 2231,3151 is 23
Step 1: Since 3151 > 2231, we apply the division lemma to 3151 and 2231, to get
3151 = 2231 x 1 + 920
Step 2: Since the reminder 2231 ≠ 0, we apply division lemma to 920 and 2231, to get
2231 = 920 x 2 + 391
Step 3: We consider the new divisor 920 and the new remainder 391, and apply the division lemma to get
920 = 391 x 2 + 138
We consider the new divisor 391 and the new remainder 138,and apply the division lemma to get
391 = 138 x 2 + 115
We consider the new divisor 138 and the new remainder 115,and apply the division lemma to get
138 = 115 x 1 + 23
We consider the new divisor 115 and the new remainder 23,and apply the division lemma to get
115 = 23 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 2231 and 3151 is 23
Notice that 23 = HCF(115,23) = HCF(138,115) = HCF(391,138) = HCF(920,391) = HCF(2231,920) = HCF(3151,2231) .
