HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 652, 641, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 405, 652, 641, 25 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 405, 652, 641, 25 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 405, 652, 641, 25 is 1.
HCF(405, 652, 641, 25) = 1
HCF of 405, 652, 641, 25 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 405, 652, 641, 25 is 1.
Highest Common Factor of 405,652,641,25 is 1
Step 1: Since 652 > 405, we apply the division lemma to 652 and 405, to get
652 = 405 x 1 + 247
Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 247 and 405, to get
405 = 247 x 1 + 158
Step 3: We consider the new divisor 247 and the new remainder 158, and apply the division lemma to get
247 = 158 x 1 + 89
We consider the new divisor 158 and the new remainder 89,and apply the division lemma to get
158 = 89 x 1 + 69
We consider the new divisor 89 and the new remainder 69,and apply the division lemma to get
89 = 69 x 1 + 20
We consider the new divisor 69 and the new remainder 20,and apply the division lemma to get
69 = 20 x 3 + 9
We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get
20 = 9 x 2 + 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 405 and 652 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(69,20) = HCF(89,69) = HCF(158,89) = HCF(247,158) = HCF(405,247) = HCF(652,405) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 641 > 1, we apply the division lemma to 641 and 1, to get
641 = 1 x 641 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1
Notice that 1 = HCF(641,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 1, we apply the division lemma to 25 and 1, to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 25 is 1
Notice that 1 = HCF(25,1) .
