HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 363, 678, 18 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 363, 678, 18 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 363, 678, 18 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 363, 678, 18 is 3.
HCF(363, 678, 18) = 3
HCF of 363, 678, 18 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 363, 678, 18 is 3.
Highest Common Factor of 363,678,18 is 3
Step 1: Since 678 > 363, we apply the division lemma to 678 and 363, to get
678 = 363 x 1 + 315
Step 2: Since the reminder 363 ≠ 0, we apply division lemma to 315 and 363, to get
363 = 315 x 1 + 48
Step 3: We consider the new divisor 315 and the new remainder 48, and apply the division lemma to get
315 = 48 x 6 + 27
We consider the new divisor 48 and the new remainder 27,and apply the division lemma to get
48 = 27 x 1 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 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 363 and 678 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(48,27) = HCF(315,48) = HCF(363,315) = HCF(678,363) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 3, we apply the division lemma to 18 and 3, 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 3 and 18 is 3
Notice that 3 = HCF(18,3) .
