HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 618, 810, 118 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 618, 810, 118 is 2 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 618, 810, 118 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 618, 810, 118 is 2.
HCF(618, 810, 118) = 2
HCF of 618, 810, 118 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 618, 810, 118 is 2.
Highest Common Factor of 618,810,118 is 2
Step 1: Since 810 > 618, we apply the division lemma to 810 and 618, to get
810 = 618 x 1 + 192
Step 2: Since the reminder 618 ≠ 0, we apply division lemma to 192 and 618, to get
618 = 192 x 3 + 42
Step 3: We consider the new divisor 192 and the new remainder 42, and apply the division lemma to get
192 = 42 x 4 + 24
We consider the new divisor 42 and the new remainder 24,and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 618 and 810 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(192,42) = HCF(618,192) = HCF(810,618) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 118 > 6, we apply the division lemma to 118 and 6, to get
118 = 6 x 19 + 4
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get
6 = 4 x 1 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 118 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(118,6) .
