HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 303 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 303 is 3 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 768, 303 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 768, 303 is 3.

HCF(768, 303) = 3

Highest common factor (HCF) of 768, 303 is 3.

Highest Common Factor of 768,303 using Euclid's algorithm

Highest Common Factor of 768,303 is 3

Step 1: Since 768 > 303, we apply the division lemma to 768 and 303, to get

768 = 303 x 2 + 162

Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 162 and 303, to get

303 = 162 x 1 + 141

Step 3: We consider the new divisor 162 and the new remainder 141, and apply the division lemma to get

162 = 141 x 1 + 21

We consider the new divisor 141 and the new remainder 21,and apply the division lemma to get

141 = 21 x 6 + 15

We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get

21 = 15 x 1 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 768 and 303 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(141,21) = HCF(162,141) = HCF(303,162) = HCF(768,303) .
