HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 261 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 453, 261 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, 261 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, 261 is 3.
HCF(453, 261) = 3
HCF of 453, 261 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, 261 is 3.
Highest Common Factor of 453,261 is 3
Step 1: Since 453 > 261, we apply the division lemma to 453 and 261, to get
453 = 261 x 1 + 192
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 192 and 261, to get
261 = 192 x 1 + 69
Step 3: We consider the new divisor 192 and the new remainder 69, and apply the division lemma to get
192 = 69 x 2 + 54
We consider the new divisor 69 and the new remainder 54,and apply the division lemma to get
69 = 54 x 1 + 15
We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get
54 = 15 x 3 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 261 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(69,54) = HCF(192,69) = HCF(261,192) = HCF(453,261) .
