HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 322, 493 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 322, 493 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 322, 493 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 322, 493 is 1.

HCF(322, 493) = 1

Highest common factor (HCF) of 322, 493 is 1.

Highest Common Factor of 322,493 using Euclid's algorithm

Highest Common Factor of 322,493 is 1

Step 1: Since 493 > 322, we apply the division lemma to 493 and 322, to get

493 = 322 x 1 + 171

Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 171 and 322, to get

322 = 171 x 1 + 151

Step 3: We consider the new divisor 171 and the new remainder 151, and apply the division lemma to get

171 = 151 x 1 + 20

We consider the new divisor 151 and the new remainder 20,and apply the division lemma to get

151 = 20 x 7 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 322 and 493 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(151,20) = HCF(171,151) = HCF(322,171) = HCF(493,322) .
