HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 186, 198 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 627, 186, 198 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 627, 186, 198 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 627, 186, 198 is 3.
HCF(627, 186, 198) = 3
HCF of 627, 186, 198 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 627, 186, 198 is 3.
Highest Common Factor of 627,186,198 is 3
Step 1: Since 627 > 186, we apply the division lemma to 627 and 186, to get
627 = 186 x 3 + 69
Step 2: Since the reminder 186 ≠ 0, we apply division lemma to 69 and 186, to get
186 = 69 x 2 + 48
Step 3: We consider the new divisor 69 and the new remainder 48, and apply the division lemma to get
69 = 48 x 1 + 21
We consider the new divisor 48 and the new remainder 21,and apply the division lemma to get
48 = 21 x 2 + 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 627 and 186 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(48,21) = HCF(69,48) = HCF(186,69) = HCF(627,186) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 198 > 3, we apply the division lemma to 198 and 3, to get
198 = 3 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 198 is 3
Notice that 3 = HCF(198,3) .
