HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 303 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 303 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 497, 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 497, 303 is 1.

HCF(497, 303) = 1

Highest common factor (HCF) of 497, 303 is 1.

Highest Common Factor of 497,303 using Euclid's algorithm

Highest Common Factor of 497,303 is 1

Step 1: Since 497 > 303, we apply the division lemma to 497 and 303, to get

497 = 303 x 1 + 194

Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 194 and 303, to get

303 = 194 x 1 + 109

Step 3: We consider the new divisor 194 and the new remainder 109, and apply the division lemma to get

194 = 109 x 1 + 85

We consider the new divisor 109 and the new remainder 85,and apply the division lemma to get

109 = 85 x 1 + 24

We consider the new divisor 85 and the new remainder 24,and apply the division lemma to get

85 = 24 x 3 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 303 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(85,24) = HCF(109,85) = HCF(194,109) = HCF(303,194) = HCF(497,303) .
