HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 489, 131, 269 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 489, 131, 269 is 1 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 489, 131, 269 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 489, 131, 269 is 1.
HCF(489, 131, 269) = 1
HCF of 489, 131, 269 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 489, 131, 269 is 1.
Highest Common Factor of 489,131,269 is 1
Step 1: Since 489 > 131, we apply the division lemma to 489 and 131, to get
489 = 131 x 3 + 96
Step 2: Since the reminder 131 ≠ 0, we apply division lemma to 96 and 131, to get
131 = 96 x 1 + 35
Step 3: We consider the new divisor 96 and the new remainder 35, and apply the division lemma to get
96 = 35 x 2 + 26
We consider the new divisor 35 and the new remainder 26,and apply the division lemma to get
35 = 26 x 1 + 9
We consider the new divisor 26 and the new remainder 9,and apply the division lemma to get
26 = 9 x 2 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 489 and 131 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(26,9) = HCF(35,26) = HCF(96,35) = HCF(131,96) = HCF(489,131) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 269 > 1, we apply the division lemma to 269 and 1, to get
269 = 1 x 269 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 269 is 1
Notice that 1 = HCF(269,1) .
