HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 624, 301 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 624, 301 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 868, 624, 301 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 868, 624, 301 is 1.
HCF(868, 624, 301) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 624, 301 is 1.
Step 1: Since 868 > 624, we apply the division lemma to 868 and 624, to get
868 = 624 x 1 + 244
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 244 and 624, to get
624 = 244 x 2 + 136
Step 3: We consider the new divisor 244 and the new remainder 136, and apply the division lemma to get
244 = 136 x 1 + 108
We consider the new divisor 136 and the new remainder 108,and apply the division lemma to get
136 = 108 x 1 + 28
We consider the new divisor 108 and the new remainder 28,and apply the division lemma to get
108 = 28 x 3 + 24
We consider the new divisor 28 and the new remainder 24,and apply the division lemma to get
28 = 24 x 1 + 4
We consider the new divisor 24 and the new remainder 4,and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 868 and 624 is 4
Notice that 4 = HCF(24,4) = HCF(28,24) = HCF(108,28) = HCF(136,108) = HCF(244,136) = HCF(624,244) = HCF(868,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 301 > 4, we apply the division lemma to 301 and 4, to get
301 = 4 x 75 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 301 is 1
Notice that 1 = HCF(4,1) = HCF(301,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 868, 624, 301?
Answer: HCF of 868, 624, 301 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 868, 624, 301 using Euclid's Algorithm?
Answer: For arbitrary numbers 868, 624, 301 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
