HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 252, 119 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 252, 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 636, 252, 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 636, 252, 119 is 1.
HCF(636, 252, 119) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 252, 119 is 1.
Step 1: Since 636 > 252, we apply the division lemma to 636 and 252, to get
636 = 252 x 2 + 132
Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 132 and 252, to get
252 = 132 x 1 + 120
Step 3: We consider the new divisor 132 and the new remainder 120, and apply the division lemma to get
132 = 120 x 1 + 12
We consider the new divisor 120 and the new remainder 12, and apply the division lemma to get
120 = 12 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 636 and 252 is 12
Notice that 12 = HCF(120,12) = HCF(132,120) = HCF(252,132) = HCF(636,252) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 119 > 12, we apply the division lemma to 119 and 12, to get
119 = 12 x 9 + 11
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 11 and 12, to get
12 = 11 x 1 + 1
Step 3: We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 119 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(119,12) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 636, 252, 119?
Answer: HCF of 636, 252, 119 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 636, 252, 119 using Euclid's Algorithm?
Answer: For arbitrary numbers 636, 252, 119 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
