HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 186, 479, 119 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 186, 479, 119 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 186, 479, 119 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 186, 479, 119 is 1.
HCF(186, 479, 119) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 186, 479, 119 is 1.
Step 1: Since 479 > 186, we apply the division lemma to 479 and 186, to get
479 = 186 x 2 + 107
Step 2: Since the reminder 186 ≠ 0, we apply division lemma to 107 and 186, to get
186 = 107 x 1 + 79
Step 3: We consider the new divisor 107 and the new remainder 79, and apply the division lemma to get
107 = 79 x 1 + 28
We consider the new divisor 79 and the new remainder 28,and apply the division lemma to get
79 = 28 x 2 + 23
We consider the new divisor 28 and the new remainder 23,and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 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 186 and 479 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(79,28) = HCF(107,79) = HCF(186,107) = HCF(479,186) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 119 > 1, we apply the division lemma to 119 and 1, to get
119 = 1 x 119 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 119 is 1
Notice that 1 = HCF(119,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 186, 479, 119?
Answer: HCF of 186, 479, 119 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 186, 479, 119 using Euclid's Algorithm?
