HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 409, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 628, 409, 551 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 628, 409, 551 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 628, 409, 551 is 1.

HCF(628, 409, 551) = 1

HCF of 628, 409, 551 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 628, 409, 551 is 1.

Highest Common Factor of 628,409,551 using Euclid's algorithm

Highest Common Factor of 628,409,551 is 1

Step 1: Since 628 > 409, we apply the division lemma to 628 and 409, to get

628 = 409 x 1 + 219

Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 219 and 409, to get

409 = 219 x 1 + 190

Step 3: We consider the new divisor 219 and the new remainder 190, and apply the division lemma to get

219 = 190 x 1 + 29

We consider the new divisor 190 and the new remainder 29,and apply the division lemma to get

190 = 29 x 6 + 16

We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get

29 = 16 x 1 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

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 628 and 409 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(190,29) = HCF(219,190) = HCF(409,219) = HCF(628,409) .

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

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

551 = 1 x 551 + 0

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

Notice that 1 = HCF(551,1) .
