HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 791, 863, 716 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 791, 863, 716 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 774, 791, 863, 716 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 774, 791, 863, 716 is 1.
HCF(774, 791, 863, 716) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 791, 863, 716 is 1.
Step 1: Since 791 > 774, we apply the division lemma to 791 and 774, to get
791 = 774 x 1 + 17
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 17 and 774, to get
774 = 17 x 45 + 9
Step 3: We consider the new divisor 17 and the new remainder 9, and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 774 and 791 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(774,17) = HCF(791,774) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get
863 = 1 x 863 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1
Notice that 1 = HCF(863,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 1, we apply the division lemma to 716 and 1, to get
716 = 1 x 716 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 716 is 1
Notice that 1 = HCF(716,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 774, 791, 863, 716?
Answer: HCF of 774, 791, 863, 716 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 774, 791, 863, 716 using Euclid's Algorithm?
Answer: For arbitrary numbers 774, 791, 863, 716 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
