HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 681, 737 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 494, 681, 737 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, 681, 737 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, 681, 737 is 1.

HCF(494, 681, 737) = 1

Highest common factor (HCF) of 494, 681, 737 is 1.

Highest Common Factor of 494,681,737 using Euclid's algorithm

Highest Common Factor of 494,681,737 is 1

Step 1: Since 681 > 494, we apply the division lemma to 681 and 494, to get

681 = 494 x 1 + 187

Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 187 and 494, to get

494 = 187 x 2 + 120

Step 3: We consider the new divisor 187 and the new remainder 120, and apply the division lemma to get

187 = 120 x 1 + 67

We consider the new divisor 120 and the new remainder 67,and apply the division lemma to get

120 = 67 x 1 + 53

We consider the new divisor 67 and the new remainder 53,and apply the division lemma to get

67 = 53 x 1 + 14

We consider the new divisor 53 and the new remainder 14,and apply the division lemma to get

53 = 14 x 3 + 11

We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get

14 = 11 x 1 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 494 and 681 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(53,14) = HCF(67,53) = HCF(120,67) = HCF(187,120) = HCF(494,187) = HCF(681,494) .

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

Step 1: Since 737 > 1, we apply the division lemma to 737 and 1, to get

737 = 1 x 737 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 737 is 1

Notice that 1 = HCF(737,1) .
