HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 907, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 907, 127 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 791, 907, 127 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 791, 907, 127 is 1.
HCF(791, 907, 127) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 907, 127 is 1.
Step 1: Since 907 > 791, we apply the division lemma to 907 and 791, to get
907 = 791 x 1 + 116
Step 2: Since the reminder 791 ≠ 0, we apply division lemma to 116 and 791, to get
791 = 116 x 6 + 95
Step 3: We consider the new divisor 116 and the new remainder 95, and apply the division lemma to get
116 = 95 x 1 + 21
We consider the new divisor 95 and the new remainder 21,and apply the division lemma to get
95 = 21 x 4 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 907 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(95,21) = HCF(116,95) = HCF(791,116) = HCF(907,791) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 127 > 1, we apply the division lemma to 127 and 1, to get
127 = 1 x 127 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 127 is 1
Notice that 1 = HCF(127,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 791, 907, 127?
Answer: HCF of 791, 907, 127 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 791, 907, 127 using Euclid's Algorithm?
Answer: For arbitrary numbers 791, 907, 127 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
