HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 139, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 139, 399 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, 399 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, 399 is 1.
HCF(139, 399) = 1
HCF of 139, 399 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, 399 is 1.
Highest Common Factor of 139,399 is 1
Step 1: Since 399 > 139, we apply the division lemma to 399 and 139, to get
399 = 139 x 2 + 121
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 121 and 139, to get
139 = 121 x 1 + 18
Step 3: We consider the new divisor 121 and the new remainder 18, and apply the division lemma to get
121 = 18 x 6 + 13
We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get
18 = 13 x 1 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 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 399 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(121,18) = HCF(139,121) = HCF(399,139) .
