HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 905, 593 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 490, 905, 593 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 490, 905, 593 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 490, 905, 593 is 1.

HCF(490, 905, 593) = 1

Highest common factor (HCF) of 490, 905, 593 is 1.

Highest Common Factor of 490,905,593 using Euclid's algorithm

Highest Common Factor of 490,905,593 is 1

Step 1: Since 905 > 490, we apply the division lemma to 905 and 490, to get

905 = 490 x 1 + 415

Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 415 and 490, to get

490 = 415 x 1 + 75

Step 3: We consider the new divisor 415 and the new remainder 75, and apply the division lemma to get

415 = 75 x 5 + 40

We consider the new divisor 75 and the new remainder 40,and apply the division lemma to get

75 = 40 x 1 + 35

We consider the new divisor 40 and the new remainder 35,and apply the division lemma to get

40 = 35 x 1 + 5

We consider the new divisor 35 and the new remainder 5,and apply the division lemma to get

35 = 5 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 490 and 905 is 5

Notice that 5 = HCF(35,5) = HCF(40,35) = HCF(75,40) = HCF(415,75) = HCF(490,415) = HCF(905,490) .

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

Step 1: Since 593 > 5, we apply the division lemma to 593 and 5, to get

593 = 5 x 118 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: 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 5 and 593 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(593,5) .
