HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 699, 135 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 493, 699, 135 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 493, 699, 135 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 493, 699, 135 is 1.

HCF(493, 699, 135) = 1

Highest common factor (HCF) of 493, 699, 135 is 1.

Highest Common Factor of 493,699,135 using Euclid's algorithm

Highest Common Factor of 493,699,135 is 1

Step 1: Since 699 > 493, we apply the division lemma to 699 and 493, to get

699 = 493 x 1 + 206

Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 206 and 493, to get

493 = 206 x 2 + 81

Step 3: We consider the new divisor 206 and the new remainder 81, and apply the division lemma to get

206 = 81 x 2 + 44

We consider the new divisor 81 and the new remainder 44,and apply the division lemma to get

81 = 44 x 1 + 37

We consider the new divisor 44 and the new remainder 37,and apply the division lemma to get

44 = 37 x 1 + 7

We consider the new divisor 37 and the new remainder 7,and apply the division lemma to get

37 = 7 x 5 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 493 and 699 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(37,7) = HCF(44,37) = HCF(81,44) = HCF(206,81) = HCF(493,206) = HCF(699,493) .

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

Step 1: Since 135 > 1, we apply the division lemma to 135 and 1, to get

135 = 1 x 135 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 135 is 1

Notice that 1 = HCF(135,1) .
