HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 81618 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 81618 is 6 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 480, 81618 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 480, 81618 is 6.
HCF(480, 81618) = 6
HCF of 480, 81618 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 480, 81618 is 6.
Highest Common Factor of 480,81618 is 6
Step 1: Since 81618 > 480, we apply the division lemma to 81618 and 480, to get
81618 = 480 x 170 + 18
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 18 and 480, to get
480 = 18 x 26 + 12
Step 3: We consider the new divisor 18 and the new remainder 12, and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 480 and 81618 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(480,18) = HCF(81618,480) .
