HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 479, 283 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 479, 283 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, 479, 283 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, 479, 283 is 1.
HCF(788, 479, 283) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 479, 283 is 1.
Step 1: Since 788 > 479, we apply the division lemma to 788 and 479, to get
788 = 479 x 1 + 309
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 309 and 479, to get
479 = 309 x 1 + 170
Step 3: We consider the new divisor 309 and the new remainder 170, and apply the division lemma to get
309 = 170 x 1 + 139
We consider the new divisor 170 and the new remainder 139,and apply the division lemma to get
170 = 139 x 1 + 31
We consider the new divisor 139 and the new remainder 31,and apply the division lemma to get
139 = 31 x 4 + 15
We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get
31 = 15 x 2 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 788 and 479 is 1
Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(139,31) = HCF(170,139) = HCF(309,170) = HCF(479,309) = HCF(788,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 283 > 1, we apply the division lemma to 283 and 1, to get
283 = 1 x 283 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 283 is 1
Notice that 1 = HCF(283,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 788, 479, 283?
Answer: HCF of 788, 479, 283 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 788, 479, 283 using Euclid's Algorithm?
Answer: For arbitrary numbers 788, 479, 283 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
