HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 27981 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 27981 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, 27981 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, 27981 is 3.
HCF(453, 27981) = 3
HCF of 453, 27981 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, 27981 is 3.
Highest Common Factor of 453,27981 is 3
Step 1: Since 27981 > 453, we apply the division lemma to 27981 and 453, to get
27981 = 453 x 61 + 348
Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 348 and 453, to get
453 = 348 x 1 + 105
Step 3: We consider the new divisor 348 and the new remainder 105, and apply the division lemma to get
348 = 105 x 3 + 33
We consider the new divisor 105 and the new remainder 33,and apply the division lemma to get
105 = 33 x 3 + 6
We consider the new divisor 33 and the new remainder 6,and apply the division lemma to get
33 = 6 x 5 + 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 27981 is 3
Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(105,33) = HCF(348,105) = HCF(453,348) = HCF(27981,453) .
