HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 27, 421, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 27, 421, 580 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 27, 421, 580 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 27, 421, 580 is 1.

HCF(27, 421, 580) = 1

HCF of 27, 421, 580 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 27, 421, 580 is 1.

Highest Common Factor of 27,421,580 using Euclid's algorithm

Highest Common Factor of 27,421,580 is 1

Step 1: Since 421 > 27, we apply the division lemma to 421 and 27, to get

421 = 27 x 15 + 16

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 16 and 27, to get

27 = 16 x 1 + 11

Step 3: We consider the new divisor 16 and the new remainder 11, and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 421 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(421,27) .


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

Step 1: Since 580 > 1, we apply the division lemma to 580 and 1, to get

580 = 1 x 580 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 580 is 1

Notice that 1 = HCF(580,1) .
