HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 5801, 1994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 5801, 1994 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 369, 5801, 1994 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 369, 5801, 1994 is 1.
HCF(369, 5801, 1994) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 369, 5801, 1994 is 1.
Step 1: Since 5801 > 369, we apply the division lemma to 5801 and 369, to get
5801 = 369 x 15 + 266
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 266 and 369, to get
369 = 266 x 1 + 103
Step 3: We consider the new divisor 266 and the new remainder 103, and apply the division lemma to get
266 = 103 x 2 + 60
We consider the new divisor 103 and the new remainder 60,and apply the division lemma to get
103 = 60 x 1 + 43
We consider the new divisor 60 and the new remainder 43,and apply the division lemma to get
60 = 43 x 1 + 17
We consider the new divisor 43 and the new remainder 17,and apply the division lemma to get
43 = 17 x 2 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 369 and 5801 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(43,17) = HCF(60,43) = HCF(103,60) = HCF(266,103) = HCF(369,266) = HCF(5801,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1994 > 1, we apply the division lemma to 1994 and 1, to get
1994 = 1 x 1994 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1994 is 1
Notice that 1 = HCF(1994,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
