HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 188, 452, 540, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 188, 452, 540, 221 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 188, 452, 540, 221 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 188, 452, 540, 221 is 1.
HCF(188, 452, 540, 221) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 188, 452, 540, 221 is 1.
Step 1: Since 452 > 188, we apply the division lemma to 452 and 188, to get
452 = 188 x 2 + 76
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 76 and 188, to get
188 = 76 x 2 + 36
Step 3: We consider the new divisor 76 and the new remainder 36, and apply the division lemma to get
76 = 36 x 2 + 4
We consider the new divisor 36 and the new remainder 4, and apply the division lemma to get
36 = 4 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 188 and 452 is 4
Notice that 4 = HCF(36,4) = HCF(76,36) = HCF(188,76) = HCF(452,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 4, we apply the division lemma to 540 and 4, to get
540 = 4 x 135 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 540 is 4
Notice that 4 = HCF(540,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 221 > 4, we apply the division lemma to 221 and 4, to get
221 = 4 x 55 + 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 221 is 1
Notice that 1 = HCF(4,1) = HCF(221,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 188, 452, 540, 221?
Answer: HCF of 188, 452, 540, 221 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 188, 452, 540, 221 using Euclid's Algorithm?
Answer: For arbitrary numbers 188, 452, 540, 221 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
