HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 751, 440, 122 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 751, 440, 122 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 751, 440, 122 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 751, 440, 122 is 1.
HCF(751, 440, 122) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 751, 440, 122 is 1.
Step 1: Since 751 > 440, we apply the division lemma to 751 and 440, to get
751 = 440 x 1 + 311
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 311 and 440, to get
440 = 311 x 1 + 129
Step 3: We consider the new divisor 311 and the new remainder 129, and apply the division lemma to get
311 = 129 x 2 + 53
We consider the new divisor 129 and the new remainder 53,and apply the division lemma to get
129 = 53 x 2 + 23
We consider the new divisor 53 and the new remainder 23,and apply the division lemma to get
53 = 23 x 2 + 7
We consider the new divisor 23 and the new remainder 7,and apply the division lemma to get
23 = 7 x 3 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 751 and 440 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(53,23) = HCF(129,53) = HCF(311,129) = HCF(440,311) = HCF(751,440) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 122 > 1, we apply the division lemma to 122 and 1, to get
122 = 1 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 122 is 1
Notice that 1 = HCF(122,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 751, 440, 122?
Answer: HCF of 751, 440, 122 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 751, 440, 122 using Euclid's Algorithm?
Answer: For arbitrary numbers 751, 440, 122 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
