HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 379, 353, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 379, 353, 181 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 82, 379, 353, 181 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 82, 379, 353, 181 is 1.
HCF(82, 379, 353, 181) = 1
HCF of 82, 379, 353, 181 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 82, 379, 353, 181 is 1.
Highest Common Factor of 82,379,353,181 is 1
Step 1: Since 379 > 82, we apply the division lemma to 379 and 82, to get
379 = 82 x 4 + 51
Step 2: Since the reminder 82 ≠ 0, we apply division lemma to 51 and 82, to get
82 = 51 x 1 + 31
Step 3: We consider the new divisor 51 and the new remainder 31, and apply the division lemma to get
51 = 31 x 1 + 20
We consider the new divisor 31 and the new remainder 20,and apply the division lemma to get
31 = 20 x 1 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 82 and 379 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(31,20) = HCF(51,31) = HCF(82,51) = HCF(379,82) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 1, we apply the division lemma to 353 and 1, to get
353 = 1 x 353 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 353 is 1
Notice that 1 = HCF(353,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 1, we apply the division lemma to 181 and 1, to get
181 = 1 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1
Notice that 1 = HCF(181,1) .
