HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 800 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 557, 800 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 557, 800 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 557, 800 is 1.

HCF(557, 800) = 1

Highest common factor (HCF) of 557, 800 is 1.

Highest Common Factor of 557,800 using Euclid's algorithm

Highest Common Factor of 557,800 is 1

Step 1: Since 800 > 557, we apply the division lemma to 800 and 557, to get

800 = 557 x 1 + 243

Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 243 and 557, to get

557 = 243 x 2 + 71

Step 3: We consider the new divisor 243 and the new remainder 71, and apply the division lemma to get

243 = 71 x 3 + 30

We consider the new divisor 71 and the new remainder 30,and apply the division lemma to get

71 = 30 x 2 + 11

We consider the new divisor 30 and the new remainder 11,and apply the division lemma to get

30 = 11 x 2 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 557 and 800 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(30,11) = HCF(71,30) = HCF(243,71) = HCF(557,243) = HCF(800,557) .
