HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 998, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 998, 368 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 747, 998, 368 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 747, 998, 368 is 1.
HCF(747, 998, 368) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 998, 368 is 1.
Step 1: Since 998 > 747, we apply the division lemma to 998 and 747, to get
998 = 747 x 1 + 251
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 251 and 747, to get
747 = 251 x 2 + 245
Step 3: We consider the new divisor 251 and the new remainder 245, and apply the division lemma to get
251 = 245 x 1 + 6
We consider the new divisor 245 and the new remainder 6,and apply the division lemma to get
245 = 6 x 40 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 747 and 998 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(245,6) = HCF(251,245) = HCF(747,251) = HCF(998,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 368 > 1, we apply the division lemma to 368 and 1, to get
368 = 1 x 368 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 368 is 1
Notice that 1 = HCF(368,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 747, 998, 368?
Answer: HCF of 747, 998, 368 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 747, 998, 368 using Euclid's Algorithm?
Answer: For arbitrary numbers 747, 998, 368 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
