HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 431, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 431, 727 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 788, 431, 727 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 788, 431, 727 is 1.
HCF(788, 431, 727) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 431, 727 is 1.
Step 1: Since 788 > 431, we apply the division lemma to 788 and 431, to get
788 = 431 x 1 + 357
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 357 and 431, to get
431 = 357 x 1 + 74
Step 3: We consider the new divisor 357 and the new remainder 74, and apply the division lemma to get
357 = 74 x 4 + 61
We consider the new divisor 74 and the new remainder 61,and apply the division lemma to get
74 = 61 x 1 + 13
We consider the new divisor 61 and the new remainder 13,and apply the division lemma to get
61 = 13 x 4 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 788 and 431 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(61,13) = HCF(74,61) = HCF(357,74) = HCF(431,357) = HCF(788,431) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 727 > 1, we apply the division lemma to 727 and 1, to get
727 = 1 x 727 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 727 is 1
Notice that 1 = HCF(727,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 788, 431, 727?
Answer: HCF of 788, 431, 727 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 788, 431, 727 using Euclid's Algorithm?
Answer: For arbitrary numbers 788, 431, 727 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
