HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 808, 789, 408 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 278, 808, 789, 408 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 278, 808, 789, 408 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 278, 808, 789, 408 is 1.

HCF(278, 808, 789, 408) = 1

Highest common factor (HCF) of 278, 808, 789, 408 is 1.

Highest Common Factor of 278,808,789,408 using Euclid's algorithm

Highest Common Factor of 278,808,789,408 is 1

Step 1: Since 808 > 278, we apply the division lemma to 808 and 278, to get

808 = 278 x 2 + 252

Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 252 and 278, to get

278 = 252 x 1 + 26

Step 3: We consider the new divisor 252 and the new remainder 26, and apply the division lemma to get

252 = 26 x 9 + 18

We consider the new divisor 26 and the new remainder 18,and apply the division lemma to get

26 = 18 x 1 + 8

We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get

18 = 8 x 2 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 808 is 2

Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(26,18) = HCF(252,26) = HCF(278,252) = HCF(808,278) .

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

Step 1: Since 789 > 2, we apply the division lemma to 789 and 2, to get

789 = 2 x 394 + 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 789 is 1

Notice that 1 = HCF(2,1) = HCF(789,2) .

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

Step 1: Since 408 > 1, we apply the division lemma to 408 and 1, to get

408 = 1 x 408 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 408 is 1

Notice that 1 = HCF(408,1) .
