HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 846, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 846, 728 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, 846, 728 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, 846, 728 is 1.

HCF(555, 846, 728) = 1

Highest common factor (HCF) of 555, 846, 728 is 1.

Highest Common Factor of 555,846,728 using Euclid's algorithm

Highest Common Factor of 555,846,728 is 1

Step 1: Since 846 > 555, we apply the division lemma to 846 and 555, to get

846 = 555 x 1 + 291

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 291 and 555, to get

555 = 291 x 1 + 264

Step 3: We consider the new divisor 291 and the new remainder 264, and apply the division lemma to get

291 = 264 x 1 + 27

We consider the new divisor 264 and the new remainder 27,and apply the division lemma to get

264 = 27 x 9 + 21

We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get

27 = 21 x 1 + 6

We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get

21 = 6 x 3 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 555 and 846 is 3

Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(264,27) = HCF(291,264) = HCF(555,291) = HCF(846,555) .

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

Step 1: Since 728 > 3, we apply the division lemma to 728 and 3, to get

728 = 3 x 242 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 728 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(728,3) .
