HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 989, 504 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 989, 504 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 555, 989, 504 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 555, 989, 504 is 1.

HCF(555, 989, 504) = 1

Highest common factor (HCF) of 555, 989, 504 is 1.

Highest Common Factor of 555,989,504 using Euclid's algorithm

Highest Common Factor of 555,989,504 is 1

Step 1: Since 989 > 555, we apply the division lemma to 989 and 555, to get

989 = 555 x 1 + 434

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 434 and 555, to get

555 = 434 x 1 + 121

Step 3: We consider the new divisor 434 and the new remainder 121, and apply the division lemma to get

434 = 121 x 3 + 71

We consider the new divisor 121 and the new remainder 71,and apply the division lemma to get

121 = 71 x 1 + 50

We consider the new divisor 71 and the new remainder 50,and apply the division lemma to get

71 = 50 x 1 + 21

We consider the new divisor 50 and the new remainder 21,and apply the division lemma to get

50 = 21 x 2 + 8

We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get

21 = 8 x 2 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 555 and 989 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(50,21) = HCF(71,50) = HCF(121,71) = HCF(434,121) = HCF(555,434) = HCF(989,555) .

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

Step 1: Since 504 > 1, we apply the division lemma to 504 and 1, to get

504 = 1 x 504 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 504 is 1

Notice that 1 = HCF(504,1) .
