HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 459 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 459 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 630, 459 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 630, 459 is 9.
HCF(630, 459) = 9
HCF of 630, 459 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 459 is 9.
Highest Common Factor of 630,459 is 9
Step 1: Since 630 > 459, we apply the division lemma to 630 and 459, to get
630 = 459 x 1 + 171
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 171 and 459, to get
459 = 171 x 2 + 117
Step 3: We consider the new divisor 171 and the new remainder 117, and apply the division lemma to get
171 = 117 x 1 + 54
We consider the new divisor 117 and the new remainder 54,and apply the division lemma to get
117 = 54 x 2 + 9
We consider the new divisor 54 and the new remainder 9,and apply the division lemma to get
54 = 9 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 630 and 459 is 9
Notice that 9 = HCF(54,9) = HCF(117,54) = HCF(171,117) = HCF(459,171) = HCF(630,459) .
