HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 538, 501, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 538, 501, 481 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 165, 538, 501, 481 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 165, 538, 501, 481 is 1.
HCF(165, 538, 501, 481) = 1
HCF of 165, 538, 501, 481 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 538, 501, 481 is 1.
Highest Common Factor of 165,538,501,481 is 1
Step 1: Since 538 > 165, we apply the division lemma to 538 and 165, to get
538 = 165 x 3 + 43
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 43 and 165, to get
165 = 43 x 3 + 36
Step 3: We consider the new divisor 43 and the new remainder 36, and apply the division lemma to get
43 = 36 x 1 + 7
We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get
36 = 7 x 5 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 165 and 538 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(165,43) = HCF(538,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 501 > 1, we apply the division lemma to 501 and 1, to get
501 = 1 x 501 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 501 is 1
Notice that 1 = HCF(501,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 481 > 1, we apply the division lemma to 481 and 1, to get
481 = 1 x 481 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 481 is 1
Notice that 1 = HCF(481,1) .
