HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 291, 571, 105 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 291, 571, 105 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 790, 291, 571, 105 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 790, 291, 571, 105 is 1.
HCF(790, 291, 571, 105) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 291, 571, 105 is 1.
Step 1: Since 790 > 291, we apply the division lemma to 790 and 291, to get
790 = 291 x 2 + 208
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 208 and 291, to get
291 = 208 x 1 + 83
Step 3: We consider the new divisor 208 and the new remainder 83, and apply the division lemma to get
208 = 83 x 2 + 42
We consider the new divisor 83 and the new remainder 42,and apply the division lemma to get
83 = 42 x 1 + 41
We consider the new divisor 42 and the new remainder 41,and apply the division lemma to get
42 = 41 x 1 + 1
We consider the new divisor 41 and the new remainder 1,and apply the division lemma to get
41 = 1 x 41 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 790 and 291 is 1
Notice that 1 = HCF(41,1) = HCF(42,41) = HCF(83,42) = HCF(208,83) = HCF(291,208) = HCF(790,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 571 > 1, we apply the division lemma to 571 and 1, to get
571 = 1 x 571 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1
Notice that 1 = HCF(571,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 105 > 1, we apply the division lemma to 105 and 1, to get
105 = 1 x 105 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 105 is 1
Notice that 1 = HCF(105,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 790, 291, 571, 105?
Answer: HCF of 790, 291, 571, 105 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 790, 291, 571, 105 using Euclid's Algorithm?
Answer: For arbitrary numbers 790, 291, 571, 105 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
