HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 9549 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 261, 9549 is 9 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 261, 9549 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 261, 9549 is 9.
HCF(261, 9549) = 9
HCF of 261, 9549 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 261, 9549 is 9.
Highest Common Factor of 261,9549 is 9
Step 1: Since 9549 > 261, we apply the division lemma to 9549 and 261, to get
9549 = 261 x 36 + 153
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 153 and 261, to get
261 = 153 x 1 + 108
Step 3: We consider the new divisor 153 and the new remainder 108, and apply the division lemma to get
153 = 108 x 1 + 45
We consider the new divisor 108 and the new remainder 45,and apply the division lemma to get
108 = 45 x 2 + 18
We consider the new divisor 45 and the new remainder 18,and apply the division lemma to get
45 = 18 x 2 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 261 and 9549 is 9
Notice that 9 = HCF(18,9) = HCF(45,18) = HCF(108,45) = HCF(153,108) = HCF(261,153) = HCF(9549,261) .
