HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 132, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 240, 132, 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 240, 132, 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 240, 132, 221 is 1.

HCF(240, 132, 221) = 1

HCF of 240, 132, 221 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 240, 132, 221 is 1.

Highest Common Factor of 240,132,221 using Euclid's algorithm

Highest Common Factor of 240,132,221 is 1

Step 1: Since 240 > 132, we apply the division lemma to 240 and 132, to get

240 = 132 x 1 + 108

Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 108 and 132, to get

132 = 108 x 1 + 24

Step 3: We consider the new divisor 108 and the new remainder 24, and apply the division lemma to get

108 = 24 x 4 + 12

We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get

24 = 12 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 240 and 132 is 12

Notice that 12 = HCF(24,12) = HCF(108,24) = HCF(132,108) = HCF(240,132) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 221 > 12, we apply the division lemma to 221 and 12, to get

221 = 12 x 18 + 5

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 5 and 12, to get

12 = 5 x 2 + 2

Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 221 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(221,12) .
