HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 303, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 801, 303, 19 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 801, 303, 19 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 801, 303, 19 is 1.

HCF(801, 303, 19) = 1

Highest common factor (HCF) of 801, 303, 19 is 1.

Highest Common Factor of 801,303,19 using Euclid's algorithm

Highest Common Factor of 801,303,19 is 1

Step 1: Since 801 > 303, we apply the division lemma to 801 and 303, to get

801 = 303 x 2 + 195

Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 195 and 303, to get

303 = 195 x 1 + 108

Step 3: We consider the new divisor 195 and the new remainder 108, and apply the division lemma to get

195 = 108 x 1 + 87

We consider the new divisor 108 and the new remainder 87,and apply the division lemma to get

108 = 87 x 1 + 21

We consider the new divisor 87 and the new remainder 21,and apply the division lemma to get

87 = 21 x 4 + 3

We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get

21 = 3 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 801 and 303 is 3

Notice that 3 = HCF(21,3) = HCF(87,21) = HCF(108,87) = HCF(195,108) = HCF(303,195) = HCF(801,303) .


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

Step 1: Since 19 > 3, we apply the division lemma to 19 and 3, to get

19 = 3 x 6 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 19 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) .
