HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 326, 744 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 326, 744 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 722, 326, 744 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 722, 326, 744 is 2.
HCF(722, 326, 744) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 326, 744 is 2.
Step 1: Since 722 > 326, we apply the division lemma to 722 and 326, to get
722 = 326 x 2 + 70
Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 70 and 326, to get
326 = 70 x 4 + 46
Step 3: We consider the new divisor 70 and the new remainder 46, and apply the division lemma to get
70 = 46 x 1 + 24
We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get
46 = 24 x 1 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 722 and 326 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(70,46) = HCF(326,70) = HCF(722,326) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 744 > 2, we apply the division lemma to 744 and 2, to get
744 = 2 x 372 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 744 is 2
Notice that 2 = HCF(744,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 722, 326, 744?
Answer: HCF of 722, 326, 744 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 722, 326, 744 using Euclid's Algorithm?
Answer: For arbitrary numbers 722, 326, 744 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
