HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 975, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 975, 775 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 803, 975, 775 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 803, 975, 775 is 1.

HCF(803, 975, 775) = 1

HCF of 803, 975, 775 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 803, 975, 775 is 1.

Highest Common Factor of 803,975,775 using Euclid's algorithm

Highest Common Factor of 803,975,775 is 1

Step 1: Since 975 > 803, we apply the division lemma to 975 and 803, to get

975 = 803 x 1 + 172

Step 2: Since the reminder 803 ≠ 0, we apply division lemma to 172 and 803, to get

803 = 172 x 4 + 115

Step 3: We consider the new divisor 172 and the new remainder 115, and apply the division lemma to get

172 = 115 x 1 + 57

We consider the new divisor 115 and the new remainder 57,and apply the division lemma to get

115 = 57 x 2 + 1

We consider the new divisor 57 and the new remainder 1,and apply the division lemma to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 803 and 975 is 1

Notice that 1 = HCF(57,1) = HCF(115,57) = HCF(172,115) = HCF(803,172) = HCF(975,803) .

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

Step 1: Since 775 > 1, we apply the division lemma to 775 and 1, to get

775 = 1 x 775 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 775 is 1

Notice that 1 = HCF(775,1) .
