HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4323, 1507, 18622 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 4323, 1507, 18622 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 4323, 1507, 18622 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 4323, 1507, 18622 is 1.
HCF(4323, 1507, 18622) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4323, 1507, 18622 is 1.
Step 1: Since 4323 > 1507, we apply the division lemma to 4323 and 1507, to get
4323 = 1507 x 2 + 1309
Step 2: Since the reminder 1507 ≠ 0, we apply division lemma to 1309 and 1507, to get
1507 = 1309 x 1 + 198
Step 3: We consider the new divisor 1309 and the new remainder 198, and apply the division lemma to get
1309 = 198 x 6 + 121
We consider the new divisor 198 and the new remainder 121,and apply the division lemma to get
198 = 121 x 1 + 77
We consider the new divisor 121 and the new remainder 77,and apply the division lemma to get
121 = 77 x 1 + 44
We consider the new divisor 77 and the new remainder 44,and apply the division lemma to get
77 = 44 x 1 + 33
We consider the new divisor 44 and the new remainder 33,and apply the division lemma to get
44 = 33 x 1 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 4323 and 1507 is 11
Notice that 11 = HCF(33,11) = HCF(44,33) = HCF(77,44) = HCF(121,77) = HCF(198,121) = HCF(1309,198) = HCF(1507,1309) = HCF(4323,1507) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18622 > 11, we apply the division lemma to 18622 and 11, to get
18622 = 11 x 1692 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 18622 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(18622,11) .
Here are some samples of HCF using Euclid's Algorithm calculations.
