HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 177, 7939, 2131 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 177, 7939, 2131 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 177, 7939, 2131 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 177, 7939, 2131 is 1.
HCF(177, 7939, 2131) = 1
HCF of 177, 7939, 2131 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 177, 7939, 2131 is 1.
Highest Common Factor of 177,7939,2131 is 1
Step 1: Since 7939 > 177, we apply the division lemma to 7939 and 177, to get
7939 = 177 x 44 + 151
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 151 and 177, to get
177 = 151 x 1 + 26
Step 3: We consider the new divisor 151 and the new remainder 26, and apply the division lemma to get
151 = 26 x 5 + 21
We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 177 and 7939 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(151,26) = HCF(177,151) = HCF(7939,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2131 > 1, we apply the division lemma to 2131 and 1, to get
2131 = 1 x 2131 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2131 is 1
Notice that 1 = HCF(2131,1) .
