HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 768, 52, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 768, 52, 365 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 216, 768, 52, 365 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 216, 768, 52, 365 is 1.
HCF(216, 768, 52, 365) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 216, 768, 52, 365 is 1.
Step 1: Since 768 > 216, we apply the division lemma to 768 and 216, to get
768 = 216 x 3 + 120
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 120 and 216, to get
216 = 120 x 1 + 96
Step 3: We consider the new divisor 120 and the new remainder 96, and apply the division lemma to get
120 = 96 x 1 + 24
We consider the new divisor 96 and the new remainder 24, and apply the division lemma to get
96 = 24 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 216 and 768 is 24
Notice that 24 = HCF(96,24) = HCF(120,96) = HCF(216,120) = HCF(768,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 24, we apply the division lemma to 52 and 24, to get
52 = 24 x 2 + 4
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 4 and 24, to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 24 and 52 is 4
Notice that 4 = HCF(24,4) = HCF(52,24) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 365 > 4, we apply the division lemma to 365 and 4, to get
365 = 4 x 91 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 365 is 1
Notice that 1 = HCF(4,1) = HCF(365,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 216, 768, 52, 365?
Answer: HCF of 216, 768, 52, 365 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 216, 768, 52, 365 using Euclid's Algorithm?
