HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 41, 66, 79, 405 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 41, 66, 79, 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 41, 66, 79, 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 41, 66, 79, 405 is 1.
HCF(41, 66, 79, 405) = 1
HCF of 41, 66, 79, 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 41, 66, 79, 405 is 1.
Highest Common Factor of 41,66,79,405 is 1
Step 1: Since 66 > 41, we apply the division lemma to 66 and 41, to get
66 = 41 x 1 + 25
Step 2: Since the reminder 41 ≠ 0, we apply division lemma to 25 and 41, to get
41 = 25 x 1 + 16
Step 3: We consider the new divisor 25 and the new remainder 16, and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 41 and 66 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(41,25) = HCF(66,41) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 79 > 1, we apply the division lemma to 79 and 1, to get
79 = 1 x 79 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 79 is 1
Notice that 1 = HCF(79,1) .
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) .
