HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 452, 405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 452, 405 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, 452, 405 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, 452, 405 is 1.
HCF(165, 452, 405) = 1
HCF of 165, 452, 405 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, 452, 405 is 1.
Highest Common Factor of 165,452,405 is 1
Step 1: Since 452 > 165, we apply the division lemma to 452 and 165, to get
452 = 165 x 2 + 122
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 122 and 165, to get
165 = 122 x 1 + 43
Step 3: We consider the new divisor 122 and the new remainder 43, and apply the division lemma to get
122 = 43 x 2 + 36
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 452 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(122,43) = HCF(165,122) = HCF(452,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 405 > 1, we apply the division lemma to 405 and 1, to get
405 = 1 x 405 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 405 is 1
Notice that 1 = HCF(405,1) .
