HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 687, 793 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 687, 793 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, 687, 793 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, 687, 793 is 1.

HCF(497, 687, 793) = 1

Highest common factor (HCF) of 497, 687, 793 is 1.

Highest Common Factor of 497,687,793 using Euclid's algorithm

Highest Common Factor of 497,687,793 is 1

Step 1: Since 687 > 497, we apply the division lemma to 687 and 497, to get

687 = 497 x 1 + 190

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 190 and 497, to get

497 = 190 x 2 + 117

Step 3: We consider the new divisor 190 and the new remainder 117, and apply the division lemma to get

190 = 117 x 1 + 73

We consider the new divisor 117 and the new remainder 73,and apply the division lemma to get

117 = 73 x 1 + 44

We consider the new divisor 73 and the new remainder 44,and apply the division lemma to get

73 = 44 x 1 + 29

We consider the new divisor 44 and the new remainder 29,and apply the division lemma to get

44 = 29 x 1 + 15

We consider the new divisor 29 and the new remainder 15,and apply the division lemma to get

29 = 15 x 1 + 14

We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get

15 = 14 x 1 + 1

We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 687 is 1

Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(44,29) = HCF(73,44) = HCF(117,73) = HCF(190,117) = HCF(497,190) = HCF(687,497) .

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

Step 1: Since 793 > 1, we apply the division lemma to 793 and 1, to get

793 = 1 x 793 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 793 is 1

Notice that 1 = HCF(793,1) .
