HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 139, 786, 58 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 139, 786, 58 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 139, 786, 58 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 139, 786, 58 is 1.
HCF(139, 786, 58) = 1
HCF of 139, 786, 58 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 139, 786, 58 is 1.
Highest Common Factor of 139,786,58 is 1
Step 1: Since 786 > 139, we apply the division lemma to 786 and 139, to get
786 = 139 x 5 + 91
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 91 and 139, to get
139 = 91 x 1 + 48
Step 3: We consider the new divisor 91 and the new remainder 48, and apply the division lemma to get
91 = 48 x 1 + 43
We consider the new divisor 48 and the new remainder 43,and apply the division lemma to get
48 = 43 x 1 + 5
We consider the new divisor 43 and the new remainder 5,and apply the division lemma to get
43 = 5 x 8 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 139 and 786 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(48,43) = HCF(91,48) = HCF(139,91) = HCF(786,139) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 58 > 1, we apply the division lemma to 58 and 1, to get
58 = 1 x 58 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 58 is 1
Notice that 1 = HCF(58,1) .
