HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 430, 3339, 7805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 430, 3339, 7805 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 430, 3339, 7805 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 430, 3339, 7805 is 1.
HCF(430, 3339, 7805) = 1
HCF of 430, 3339, 7805 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 430, 3339, 7805 is 1.
Highest Common Factor of 430,3339,7805 is 1
Step 1: Since 3339 > 430, we apply the division lemma to 3339 and 430, to get
3339 = 430 x 7 + 329
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 329 and 430, to get
430 = 329 x 1 + 101
Step 3: We consider the new divisor 329 and the new remainder 101, and apply the division lemma to get
329 = 101 x 3 + 26
We consider the new divisor 101 and the new remainder 26,and apply the division lemma to get
101 = 26 x 3 + 23
We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get
26 = 23 x 1 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 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 430 and 3339 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(101,26) = HCF(329,101) = HCF(430,329) = HCF(3339,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7805 > 1, we apply the division lemma to 7805 and 1, to get
7805 = 1 x 7805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7805 is 1
Notice that 1 = HCF(7805,1) .
