HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 282, 489 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 282, 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 282, 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 282, 489 is 3.
HCF(282, 489) = 3
HCF of 282, 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 282, 489 is 3.
Highest Common Factor of 282,489 is 3
Step 1: Since 489 > 282, we apply the division lemma to 489 and 282, to get
489 = 282 x 1 + 207
Step 2: Since the reminder 282 ≠ 0, we apply division lemma to 207 and 282, to get
282 = 207 x 1 + 75
Step 3: We consider the new divisor 207 and the new remainder 75, and apply the division lemma to get
207 = 75 x 2 + 57
We consider the new divisor 75 and the new remainder 57,and apply the division lemma to get
75 = 57 x 1 + 18
We consider the new divisor 57 and the new remainder 18,and apply the division lemma to get
57 = 18 x 3 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 282 and 489 is 3
Notice that 3 = HCF(18,3) = HCF(57,18) = HCF(75,57) = HCF(207,75) = HCF(282,207) = HCF(489,282) .
