HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 928, 327 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 928, 327 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 720, 928, 327 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 720, 928, 327 is 1.
HCF(720, 928, 327) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 928, 327 is 1.
Step 1: Since 928 > 720, we apply the division lemma to 928 and 720, to get
928 = 720 x 1 + 208
Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 208 and 720, to get
720 = 208 x 3 + 96
Step 3: We consider the new divisor 208 and the new remainder 96, and apply the division lemma to get
208 = 96 x 2 + 16
We consider the new divisor 96 and the new remainder 16, and apply the division lemma to get
96 = 16 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 720 and 928 is 16
Notice that 16 = HCF(96,16) = HCF(208,96) = HCF(720,208) = HCF(928,720) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 327 > 16, we apply the division lemma to 327 and 16, to get
327 = 16 x 20 + 7
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 7 and 16, to get
16 = 7 x 2 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 16 and 327 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(327,16) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 720, 928, 327?
Answer: HCF of 720, 928, 327 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 720, 928, 327 using Euclid's Algorithm?
Answer: For arbitrary numbers 720, 928, 327 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
