HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 621, 627 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 993, 621, 627 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 993, 621, 627 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 993, 621, 627 is 3.
HCF(993, 621, 627) = 3
HCF of 993, 621, 627 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 993, 621, 627 is 3.
Highest Common Factor of 993,621,627 is 3
Step 1: Since 993 > 621, we apply the division lemma to 993 and 621, to get
993 = 621 x 1 + 372
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 372 and 621, to get
621 = 372 x 1 + 249
Step 3: We consider the new divisor 372 and the new remainder 249, and apply the division lemma to get
372 = 249 x 1 + 123
We consider the new divisor 249 and the new remainder 123,and apply the division lemma to get
249 = 123 x 2 + 3
We consider the new divisor 123 and the new remainder 3,and apply the division lemma to get
123 = 3 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 993 and 621 is 3
Notice that 3 = HCF(123,3) = HCF(249,123) = HCF(372,249) = HCF(621,372) = HCF(993,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 627 > 3, we apply the division lemma to 627 and 3, to get
627 = 3 x 209 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 627 is 3
Notice that 3 = HCF(627,3) .
