HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 581, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 216, 581, 312 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 216, 581, 312 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 216, 581, 312 is 1.

HCF(216, 581, 312) = 1

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

HCF of:

Highest common factor (HCF) of 216, 581, 312 is 1.

Highest Common Factor of 216,581,312 using Euclid's algorithm

Highest Common Factor of 216,581,312 is 1

Step 1: Since 581 > 216, we apply the division lemma to 581 and 216, to get

581 = 216 x 2 + 149

Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 149 and 216, to get

216 = 149 x 1 + 67

Step 3: We consider the new divisor 149 and the new remainder 67, and apply the division lemma to get

149 = 67 x 2 + 15

We consider the new divisor 67 and the new remainder 15,and apply the division lemma to get

67 = 15 x 4 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 216 and 581 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(67,15) = HCF(149,67) = HCF(216,149) = HCF(581,216) .

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

Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get

312 = 1 x 312 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1

Notice that 1 = HCF(312,1) .
