HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 904, 778 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 551, 904, 778 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 551, 904, 778 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 551, 904, 778 is 1.

HCF(551, 904, 778) = 1

Highest common factor (HCF) of 551, 904, 778 is 1.

Highest Common Factor of 551,904,778 using Euclid's algorithm

Highest Common Factor of 551,904,778 is 1

Step 1: Since 904 > 551, we apply the division lemma to 904 and 551, to get

904 = 551 x 1 + 353

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 353 and 551, to get

551 = 353 x 1 + 198

Step 3: We consider the new divisor 353 and the new remainder 198, and apply the division lemma to get

353 = 198 x 1 + 155

We consider the new divisor 198 and the new remainder 155,and apply the division lemma to get

198 = 155 x 1 + 43

We consider the new divisor 155 and the new remainder 43,and apply the division lemma to get

155 = 43 x 3 + 26

We consider the new divisor 43 and the new remainder 26,and apply the division lemma to get

43 = 26 x 1 + 17

We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get

26 = 17 x 1 + 9

We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get

17 = 9 x 1 + 8

We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get

9 = 8 x 1 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 551 and 904 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(43,26) = HCF(155,43) = HCF(198,155) = HCF(353,198) = HCF(551,353) = HCF(904,551) .

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

Step 1: Since 778 > 1, we apply the division lemma to 778 and 1, to get

778 = 1 x 778 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 778 is 1

Notice that 1 = HCF(778,1) .
