HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 143, 819, 993, 24 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 143, 819, 993, 24 is 1 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 143, 819, 993, 24 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 143, 819, 993, 24 is 1.
HCF(143, 819, 993, 24) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 143, 819, 993, 24 is 1.
Step 1: Since 819 > 143, we apply the division lemma to 819 and 143, to get
819 = 143 x 5 + 104
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 104 and 143, to get
143 = 104 x 1 + 39
Step 3: We consider the new divisor 104 and the new remainder 39, and apply the division lemma to get
104 = 39 x 2 + 26
We consider the new divisor 39 and the new remainder 26,and apply the division lemma to get
39 = 26 x 1 + 13
We consider the new divisor 26 and the new remainder 13,and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 143 and 819 is 13
Notice that 13 = HCF(26,13) = HCF(39,26) = HCF(104,39) = HCF(143,104) = HCF(819,143) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 993 > 13, we apply the division lemma to 993 and 13, to get
993 = 13 x 76 + 5
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 5 and 13, to get
13 = 5 x 2 + 3
Step 3: We consider the new divisor 5 and the new remainder 3, and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 993 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(993,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1
Notice that 1 = HCF(24,1) .
