HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 629, 803 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 494, 629, 803 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 494, 629, 803 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 494, 629, 803 is 1.

HCF(494, 629, 803) = 1

Highest common factor (HCF) of 494, 629, 803 is 1.

Highest Common Factor of 494,629,803 using Euclid's algorithm

Highest Common Factor of 494,629,803 is 1

Step 1: Since 629 > 494, we apply the division lemma to 629 and 494, to get

629 = 494 x 1 + 135

Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 135 and 494, to get

494 = 135 x 3 + 89

Step 3: We consider the new divisor 135 and the new remainder 89, and apply the division lemma to get

135 = 89 x 1 + 46

We consider the new divisor 89 and the new remainder 46,and apply the division lemma to get

89 = 46 x 1 + 43

We consider the new divisor 46 and the new remainder 43,and apply the division lemma to get

46 = 43 x 1 + 3

We consider the new divisor 43 and the new remainder 3,and apply the division lemma to get

43 = 3 x 14 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 494 and 629 is 1

Notice that 1 = HCF(3,1) = HCF(43,3) = HCF(46,43) = HCF(89,46) = HCF(135,89) = HCF(494,135) = HCF(629,494) .

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

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

803 = 1 x 803 + 0

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

Notice that 1 = HCF(803,1) .
