HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 489 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 324, 489 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 324, 489 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 324, 489 is 3.
HCF(324, 489) = 3
HCF of 324, 489 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 324, 489 is 3.
Highest Common Factor of 324,489 is 3
Step 1: Since 489 > 324, we apply the division lemma to 489 and 324, to get
489 = 324 x 1 + 165
Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 165 and 324, to get
324 = 165 x 1 + 159
Step 3: We consider the new divisor 165 and the new remainder 159, and apply the division lemma to get
165 = 159 x 1 + 6
We consider the new divisor 159 and the new remainder 6,and apply the division lemma to get
159 = 6 x 26 + 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 324 and 489 is 3
Notice that 3 = HCF(6,3) = HCF(159,6) = HCF(165,159) = HCF(324,165) = HCF(489,324) .
