HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 604, 205, 508 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 478, 604, 205, 508 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 478, 604, 205, 508 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 478, 604, 205, 508 is 1.

HCF(478, 604, 205, 508) = 1

Highest Common Factor of 478,604,205,508 using Euclid's algorithm

Highest Common Factor of 478,604,205,508 is 1

Step 1: Since 604 > 478, we apply the division lemma to 604 and 478, to get

604 = 478 x 1 + 126

Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 126 and 478, to get

478 = 126 x 3 + 100

Step 3: We consider the new divisor 126 and the new remainder 100, and apply the division lemma to get

126 = 100 x 1 + 26

We consider the new divisor 100 and the new remainder 26,and apply the division lemma to get

100 = 26 x 3 + 22

We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get

26 = 22 x 1 + 4

We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get

22 = 4 x 5 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 478 and 604 is 2

Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(100,26) = HCF(126,100) = HCF(478,126) = HCF(604,478) .

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

Step 1: Since 205 > 2, we apply the division lemma to 205 and 2, to get

205 = 2 x 102 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 205 is 1

Notice that 1 = HCF(2,1) = HCF(205,2) .

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

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

508 = 1 x 508 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 508 is 1

Notice that 1 = HCF(508,1) .
