HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 309, 405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 446, 309, 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 446, 309, 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 446, 309, 405 is 1.
HCF(446, 309, 405) = 1
HCF of 446, 309, 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 446, 309, 405 is 1.
Highest Common Factor of 446,309,405 is 1
Step 1: Since 446 > 309, we apply the division lemma to 446 and 309, to get
446 = 309 x 1 + 137
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 137 and 309, to get
309 = 137 x 2 + 35
Step 3: We consider the new divisor 137 and the new remainder 35, and apply the division lemma to get
137 = 35 x 3 + 32
We consider the new divisor 35 and the new remainder 32,and apply the division lemma to get
35 = 32 x 1 + 3
We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get
32 = 3 x 10 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 446 and 309 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(35,32) = HCF(137,35) = HCF(309,137) = HCF(446,309) .
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) .
