HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 2541 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 2541 is 3 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 453, 2541 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 453, 2541 is 3.
HCF(453, 2541) = 3
HCF of 453, 2541 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 453, 2541 is 3.
Highest Common Factor of 453,2541 is 3
Step 1: Since 2541 > 453, we apply the division lemma to 2541 and 453, to get
2541 = 453 x 5 + 276
Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 276 and 453, to get
453 = 276 x 1 + 177
Step 3: We consider the new divisor 276 and the new remainder 177, and apply the division lemma to get
276 = 177 x 1 + 99
We consider the new divisor 177 and the new remainder 99,and apply the division lemma to get
177 = 99 x 1 + 78
We consider the new divisor 99 and the new remainder 78,and apply the division lemma to get
99 = 78 x 1 + 21
We consider the new divisor 78 and the new remainder 21,and apply the division lemma to get
78 = 21 x 3 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 453 and 2541 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(78,21) = HCF(99,78) = HCF(177,99) = HCF(276,177) = HCF(453,276) = HCF(2541,453) .
