HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 664, 419 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 508, 664, 419 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 508, 664, 419 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 508, 664, 419 is 1.

HCF(508, 664, 419) = 1

HCF of 508, 664, 419 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 508, 664, 419 is 1.

Highest Common Factor of 508,664,419 using Euclid's algorithm

Highest Common Factor of 508,664,419 is 1

Step 1: Since 664 > 508, we apply the division lemma to 664 and 508, to get

664 = 508 x 1 + 156

Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 156 and 508, to get

508 = 156 x 3 + 40

Step 3: We consider the new divisor 156 and the new remainder 40, and apply the division lemma to get

156 = 40 x 3 + 36

We consider the new divisor 40 and the new remainder 36,and apply the division lemma to get

40 = 36 x 1 + 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 508 and 664 is 4

Notice that 4 = HCF(36,4) = HCF(40,36) = HCF(156,40) = HCF(508,156) = HCF(664,508) .

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

Step 1: Since 419 > 4, we apply the division lemma to 419 and 4, to get

419 = 4 x 104 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 419 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(419,4) .
