HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 684, 50 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 298, 684, 50 is 2 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 298, 684, 50 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 298, 684, 50 is 2.
HCF(298, 684, 50) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 298, 684, 50 is 2.
Step 1: Since 684 > 298, we apply the division lemma to 684 and 298, to get
684 = 298 x 2 + 88
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 88 and 298, to get
298 = 88 x 3 + 34
Step 3: We consider the new divisor 88 and the new remainder 34, and apply the division lemma to get
88 = 34 x 2 + 20
We consider the new divisor 34 and the new remainder 20,and apply the division lemma to get
34 = 20 x 1 + 14
We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 298 and 684 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(34,20) = HCF(88,34) = HCF(298,88) = HCF(684,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 50 > 2, we apply the division lemma to 50 and 2, to get
50 = 2 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 50 is 2
Notice that 2 = HCF(50,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 298, 684, 50?
Answer: HCF of 298, 684, 50 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 298, 684, 50 using Euclid's Algorithm?
Answer: For arbitrary numbers 298, 684, 50 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
