HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 93, 57, 55, 352 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 93, 57, 55, 352 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 93, 57, 55, 352 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 93, 57, 55, 352 is 1.
HCF(93, 57, 55, 352) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 93, 57, 55, 352 is 1.
Step 1: Since 93 > 57, we apply the division lemma to 93 and 57, to get
93 = 57 x 1 + 36
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 36 and 57, to get
57 = 36 x 1 + 21
Step 3: We consider the new divisor 36 and the new remainder 21, and apply the division lemma to get
36 = 21 x 1 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 93 and 57 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(36,21) = HCF(57,36) = HCF(93,57) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 3, we apply the division lemma to 55 and 3, to get
55 = 3 x 18 + 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 55 is 1
Notice that 1 = HCF(3,1) = HCF(55,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 352 > 1, we apply the division lemma to 352 and 1, to get
352 = 1 x 352 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 352 is 1
Notice that 1 = HCF(352,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 93, 57, 55, 352?
Answer: HCF of 93, 57, 55, 352 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 93, 57, 55, 352 using Euclid's Algorithm?
Answer: For arbitrary numbers 93, 57, 55, 352 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
