HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 806, 139, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 806, 139, 64 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 806, 139, 64 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 806, 139, 64 is 1.
HCF(806, 139, 64) = 1
HCF of 806, 139, 64 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 806, 139, 64 is 1.
Highest Common Factor of 806,139,64 is 1
Step 1: Since 806 > 139, we apply the division lemma to 806 and 139, to get
806 = 139 x 5 + 111
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 111 and 139, to get
139 = 111 x 1 + 28
Step 3: We consider the new divisor 111 and the new remainder 28, and apply the division lemma to get
111 = 28 x 3 + 27
We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 806 and 139 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(111,28) = HCF(139,111) = HCF(806,139) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1
Notice that 1 = HCF(64,1) .
