HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 803, 948, 378 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 803, 948, 378 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, 948, 378 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, 948, 378 is 1.

HCF(803, 948, 378) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 803, 948, 378 is 1.

Highest Common Factor of 803,948,378 using Euclid's algorithm

Highest Common Factor of 803,948,378 is 1

Step 1: Since 948 > 803, we apply the division lemma to 948 and 803, to get

948 = 803 x 1 + 145

Step 2: Since the reminder 803 ≠ 0, we apply division lemma to 145 and 803, to get

803 = 145 x 5 + 78

Step 3: We consider the new divisor 145 and the new remainder 78, and apply the division lemma to get

145 = 78 x 1 + 67

We consider the new divisor 78 and the new remainder 67,and apply the division lemma to get

78 = 67 x 1 + 11

We consider the new divisor 67 and the new remainder 11,and apply the division lemma to get

67 = 11 x 6 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 803 and 948 is 1

Notice that 1 = HCF(11,1) = HCF(67,11) = HCF(78,67) = HCF(145,78) = HCF(803,145) = HCF(948,803) .

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

Step 1: Since 378 > 1, we apply the division lemma to 378 and 1, to get

378 = 1 x 378 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 378 is 1

Notice that 1 = HCF(378,1) .
