HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 138, 601, 183 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 138, 601, 183 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 138, 601, 183 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 138, 601, 183 is 1.
HCF(138, 601, 183) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 138, 601, 183 is 1.
Step 1: Since 601 > 138, we apply the division lemma to 601 and 138, to get
601 = 138 x 4 + 49
Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 49 and 138, to get
138 = 49 x 2 + 40
Step 3: We consider the new divisor 49 and the new remainder 40, and apply the division lemma to get
49 = 40 x 1 + 9
We consider the new divisor 40 and the new remainder 9,and apply the division lemma to get
40 = 9 x 4 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 138 and 601 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(40,9) = HCF(49,40) = HCF(138,49) = HCF(601,138) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 183 > 1, we apply the division lemma to 183 and 1, to get
183 = 1 x 183 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 183 is 1
Notice that 1 = HCF(183,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 138, 601, 183?
Answer: HCF of 138, 601, 183 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 138, 601, 183 using Euclid's Algorithm?
Answer: For arbitrary numbers 138, 601, 183 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
