HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 348, 993 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 522, 348, 993 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 522, 348, 993 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 522, 348, 993 is 3.
HCF(522, 348, 993) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 522, 348, 993 is 3.
Step 1: Since 522 > 348, we apply the division lemma to 522 and 348, to get
522 = 348 x 1 + 174
Step 2: Since the reminder 348 ≠ 0, we apply division lemma to 174 and 348, to get
348 = 174 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 174, the HCF of 522 and 348 is 174
Notice that 174 = HCF(348,174) = HCF(522,348) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 993 > 174, we apply the division lemma to 993 and 174, to get
993 = 174 x 5 + 123
Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 123 and 174, to get
174 = 123 x 1 + 51
Step 3: We consider the new divisor 123 and the new remainder 51, and apply the division lemma to get
123 = 51 x 2 + 21
We consider the new divisor 51 and the new remainder 21,and apply the division lemma to get
51 = 21 x 2 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 174 and 993 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(51,21) = HCF(123,51) = HCF(174,123) = HCF(993,174) .
Here are some samples of HCF using Euclid's Algorithm calculations.
