HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 204, 357, 10, 747 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 204, 357, 10, 747 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 204, 357, 10, 747 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 204, 357, 10, 747 is 1.
HCF(204, 357, 10, 747) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 204, 357, 10, 747 is 1.
Step 1: Since 357 > 204, we apply the division lemma to 357 and 204, to get
357 = 204 x 1 + 153
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 153 and 204, to get
204 = 153 x 1 + 51
Step 3: We consider the new divisor 153 and the new remainder 51, and apply the division lemma to get
153 = 51 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 204 and 357 is 51
Notice that 51 = HCF(153,51) = HCF(204,153) = HCF(357,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 10, we apply the division lemma to 51 and 10, to get
51 = 10 x 5 + 1
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 1 and 10, 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 51 and 10 is 1
Notice that 1 = HCF(10,1) = HCF(51,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 747 > 1, we apply the division lemma to 747 and 1, to get
747 = 1 x 747 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 747 is 1
Notice that 1 = HCF(747,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 204, 357, 10, 747?
Answer: HCF of 204, 357, 10, 747 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 204, 357, 10, 747 using Euclid's Algorithm?
Answer: For arbitrary numbers 204, 357, 10, 747 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
