HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 985, 318 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 468, 985, 318 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 468, 985, 318 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 468, 985, 318 is 1.

HCF(468, 985, 318) = 1

HCF of 468, 985, 318 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 468, 985, 318 is 1.

Highest Common Factor of 468,985,318 using Euclid's algorithm

Highest Common Factor of 468,985,318 is 1

Step 1: Since 985 > 468, we apply the division lemma to 985 and 468, to get

985 = 468 x 2 + 49

Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 49 and 468, to get

468 = 49 x 9 + 27

Step 3: We consider the new divisor 49 and the new remainder 27, and apply the division lemma to get

49 = 27 x 1 + 22

We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get

27 = 22 x 1 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 468 and 985 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(468,49) = HCF(985,468) .

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

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

318 = 1 x 318 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 318 is 1

Notice that 1 = HCF(318,1) .
