HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 121, 743, 76, 567 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 121, 743, 76, 567 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 121, 743, 76, 567 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 121, 743, 76, 567 is 1.
HCF(121, 743, 76, 567) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 121, 743, 76, 567 is 1.
Step 1: Since 743 > 121, we apply the division lemma to 743 and 121, to get
743 = 121 x 6 + 17
Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 17 and 121, to get
121 = 17 x 7 + 2
Step 3: We consider the new divisor 17 and the new remainder 2, and apply the division lemma to get
17 = 2 x 8 + 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 121 and 743 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(121,17) = HCF(743,121) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1
Notice that 1 = HCF(76,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 1, we apply the division lemma to 567 and 1, to get
567 = 1 x 567 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 567 is 1
Notice that 1 = HCF(567,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 121, 743, 76, 567?
Answer: HCF of 121, 743, 76, 567 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 121, 743, 76, 567 using Euclid's Algorithm?
Answer: For arbitrary numbers 121, 743, 76, 567 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
