HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 739, 994, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 739, 994, 247 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 739, 994, 247 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 739, 994, 247 is 1.
HCF(739, 994, 247) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 739, 994, 247 is 1.
Step 1: Since 994 > 739, we apply the division lemma to 994 and 739, to get
994 = 739 x 1 + 255
Step 2: Since the reminder 739 ≠ 0, we apply division lemma to 255 and 739, to get
739 = 255 x 2 + 229
Step 3: We consider the new divisor 255 and the new remainder 229, and apply the division lemma to get
255 = 229 x 1 + 26
We consider the new divisor 229 and the new remainder 26,and apply the division lemma to get
229 = 26 x 8 + 21
We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 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 739 and 994 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(229,26) = HCF(255,229) = HCF(739,255) = HCF(994,739) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 1, we apply the division lemma to 247 and 1, to get
247 = 1 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 247 is 1
Notice that 1 = HCF(247,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 739, 994, 247?
Answer: HCF of 739, 994, 247 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 739, 994, 247 using Euclid's Algorithm?
Answer: For arbitrary numbers 739, 994, 247 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
