HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 805, 531 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 805, 531 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 318, 805, 531 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 318, 805, 531 is 1.

HCF(318, 805, 531) = 1

Highest common factor (HCF) of 318, 805, 531 is 1.

Highest Common Factor of 318,805,531 using Euclid's algorithm

Highest Common Factor of 318,805,531 is 1

Step 1: Since 805 > 318, we apply the division lemma to 805 and 318, to get

805 = 318 x 2 + 169

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 169 and 318, to get

318 = 169 x 1 + 149

Step 3: We consider the new divisor 169 and the new remainder 149, and apply the division lemma to get

169 = 149 x 1 + 20

We consider the new divisor 149 and the new remainder 20,and apply the division lemma to get

149 = 20 x 7 + 9

We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get

20 = 9 x 2 + 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 318 and 805 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(149,20) = HCF(169,149) = HCF(318,169) = HCF(805,318) .

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

Step 1: Since 531 > 1, we apply the division lemma to 531 and 1, to get

531 = 1 x 531 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 531 is 1

Notice that 1 = HCF(531,1) .
