HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 297, 803 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 557, 297, 803 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, 297, 803 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, 297, 803 is 1.

HCF(557, 297, 803) = 1

HCF of 557, 297, 803 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 557, 297, 803 is 1.

Highest Common Factor of 557,297,803 using Euclid's algorithm

Highest Common Factor of 557,297,803 is 1

Step 1: Since 557 > 297, we apply the division lemma to 557 and 297, to get

557 = 297 x 1 + 260

Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 260 and 297, to get

297 = 260 x 1 + 37

Step 3: We consider the new divisor 260 and the new remainder 37, and apply the division lemma to get

260 = 37 x 7 + 1

We consider the new divisor 37 and the new remainder 1, and apply the division lemma to get

37 = 1 x 37 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 297 is 1

Notice that 1 = HCF(37,1) = HCF(260,37) = HCF(297,260) = HCF(557,297) .


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

Step 1: Since 803 > 1, we apply the division lemma to 803 and 1, to get

803 = 1 x 803 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 803 is 1

Notice that 1 = HCF(803,1) .
