HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 580, 995, 789 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 580, 995, 789 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 580, 995, 789 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 580, 995, 789 is 1.
HCF(580, 995, 789) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 580, 995, 789 is 1.
Step 1: Since 995 > 580, we apply the division lemma to 995 and 580, to get
995 = 580 x 1 + 415
Step 2: Since the reminder 580 ≠ 0, we apply division lemma to 415 and 580, to get
580 = 415 x 1 + 165
Step 3: We consider the new divisor 415 and the new remainder 165, and apply the division lemma to get
415 = 165 x 2 + 85
We consider the new divisor 165 and the new remainder 85,and apply the division lemma to get
165 = 85 x 1 + 80
We consider the new divisor 85 and the new remainder 80,and apply the division lemma to get
85 = 80 x 1 + 5
We consider the new divisor 80 and the new remainder 5,and apply the division lemma to get
80 = 5 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 580 and 995 is 5
Notice that 5 = HCF(80,5) = HCF(85,80) = HCF(165,85) = HCF(415,165) = HCF(580,415) = HCF(995,580) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 789 > 5, we apply the division lemma to 789 and 5, to get
789 = 5 x 157 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: 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 5 and 789 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(789,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 580, 995, 789?
Answer: HCF of 580, 995, 789 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 580, 995, 789 using Euclid's Algorithm?
