HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 131, 16942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 131, 16942 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 131, 16942 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 131, 16942 is 1.
HCF(131, 16942) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 131, 16942 is 1.
Step 1: Since 16942 > 131, we apply the division lemma to 16942 and 131, to get
16942 = 131 x 129 + 43
Step 2: Since the reminder 131 ≠ 0, we apply division lemma to 43 and 131, to get
131 = 43 x 3 + 2
Step 3: We consider the new divisor 43 and the new remainder 2, and apply the division lemma to get
43 = 2 x 21 + 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 131 and 16942 is 1
Notice that 1 = HCF(2,1) = HCF(43,2) = HCF(131,43) = HCF(16942,131) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 131, 16942?
Answer: HCF of 131, 16942 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 131, 16942 using Euclid's Algorithm?
Answer: For arbitrary numbers 131, 16942 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
