HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 805, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 805, 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 542, 805, 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 542, 805, 221 is 1.

HCF(542, 805, 221) = 1

Highest common factor (HCF) of 542, 805, 221 is 1.

Highest Common Factor of 542,805,221 using Euclid's algorithm

Highest Common Factor of 542,805,221 is 1

Step 1: Since 805 > 542, we apply the division lemma to 805 and 542, to get

805 = 542 x 1 + 263

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 263 and 542, to get

542 = 263 x 2 + 16

Step 3: We consider the new divisor 263 and the new remainder 16, and apply the division lemma to get

263 = 16 x 16 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 542 and 805 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(263,16) = HCF(542,263) = HCF(805,542) .

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

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

221 = 1 x 221 + 0

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

Notice that 1 = HCF(221,1) .
