HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 3030, 7330 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 957, 3030, 7330 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 957, 3030, 7330 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 957, 3030, 7330 is 1.
HCF(957, 3030, 7330) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 957, 3030, 7330 is 1.
Step 1: Since 3030 > 957, we apply the division lemma to 3030 and 957, to get
3030 = 957 x 3 + 159
Step 2: Since the reminder 957 ≠ 0, we apply division lemma to 159 and 957, to get
957 = 159 x 6 + 3
Step 3: We consider the new divisor 159 and the new remainder 3, and apply the division lemma to get
159 = 3 x 53 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 957 and 3030 is 3
Notice that 3 = HCF(159,3) = HCF(957,159) = HCF(3030,957) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7330 > 3, we apply the division lemma to 7330 and 3, to get
7330 = 3 x 2443 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 7330 is 1
Notice that 1 = HCF(3,1) = HCF(7330,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 957, 3030, 7330?
Answer: HCF of 957, 3030, 7330 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 957, 3030, 7330 using Euclid's Algorithm?
Answer: For arbitrary numbers 957, 3030, 7330 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
