HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 576, 427, 415 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 576, 427, 415 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 576, 427, 415 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 576, 427, 415 is 1.

HCF(576, 427, 415) = 1

HCF of 576, 427, 415 using Euclid's algorithm

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

Highest common factor (HCF) of 576, 427, 415 is 1.

Highest Common Factor of 576,427,415 using Euclid's algorithm

Highest Common Factor of 576,427,415 is 1

Step 1: Since 576 > 427, we apply the division lemma to 576 and 427, to get

576 = 427 x 1 + 149

Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 149 and 427, to get

427 = 149 x 2 + 129

Step 3: We consider the new divisor 149 and the new remainder 129, and apply the division lemma to get

149 = 129 x 1 + 20

We consider the new divisor 129 and the new remainder 20,and apply the division lemma to get

129 = 20 x 6 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 576 and 427 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(129,20) = HCF(149,129) = HCF(427,149) = HCF(576,427) .

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

Step 1: Since 415 > 1, we apply the division lemma to 415 and 1, to get

415 = 1 x 415 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 415 is 1

Notice that 1 = HCF(415,1) .
