HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 899, 858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 899, 858 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, 899, 858 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, 899, 858 is 1.

HCF(555, 899, 858) = 1

Highest common factor (HCF) of 555, 899, 858 is 1.

Highest Common Factor of 555,899,858 using Euclid's algorithm

Highest Common Factor of 555,899,858 is 1

Step 1: Since 899 > 555, we apply the division lemma to 899 and 555, to get

899 = 555 x 1 + 344

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 344 and 555, to get

555 = 344 x 1 + 211

Step 3: We consider the new divisor 344 and the new remainder 211, and apply the division lemma to get

344 = 211 x 1 + 133

We consider the new divisor 211 and the new remainder 133,and apply the division lemma to get

211 = 133 x 1 + 78

We consider the new divisor 133 and the new remainder 78,and apply the division lemma to get

133 = 78 x 1 + 55

We consider the new divisor 78 and the new remainder 55,and apply the division lemma to get

78 = 55 x 1 + 23

We consider the new divisor 55 and the new remainder 23,and apply the division lemma to get

55 = 23 x 2 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 555 and 899 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(55,23) = HCF(78,55) = HCF(133,78) = HCF(211,133) = HCF(344,211) = HCF(555,344) = HCF(899,555) .

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

Step 1: Since 858 > 1, we apply the division lemma to 858 and 1, to get

858 = 1 x 858 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 858 is 1

Notice that 1 = HCF(858,1) .
