HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 414, 156 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 468, 414, 156 is 6 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 468, 414, 156 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 468, 414, 156 is 6.
HCF(468, 414, 156) = 6
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 468, 414, 156 is 6.
Step 1: Since 468 > 414, we apply the division lemma to 468 and 414, to get
468 = 414 x 1 + 54
Step 2: Since the reminder 414 ≠ 0, we apply division lemma to 54 and 414, to get
414 = 54 x 7 + 36
Step 3: We consider the new divisor 54 and the new remainder 36, and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 468 and 414 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(414,54) = HCF(468,414) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 18, we apply the division lemma to 156 and 18, to get
156 = 18 x 8 + 12
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 12 and 18, to get
18 = 12 x 1 + 6
Step 3: We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 18 and 156 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(156,18) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 468, 414, 156?
Answer: HCF of 468, 414, 156 is 6 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 468, 414, 156 using Euclid's Algorithm?
Answer: For arbitrary numbers 468, 414, 156 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
