HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 918 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 330, 918 is 6 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 330, 918 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 330, 918 is 6.

HCF(330, 918) = 6

HCF of 330, 918 using Euclid's algorithm

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

Highest common factor (HCF) of 330, 918 is 6.

Highest Common Factor of 330,918 using Euclid's algorithm

Highest Common Factor of 330,918 is 6

Step 1: Since 918 > 330, we apply the division lemma to 918 and 330, to get

918 = 330 x 2 + 258

Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 258 and 330, to get

330 = 258 x 1 + 72

Step 3: We consider the new divisor 258 and the new remainder 72, and apply the division lemma to get

258 = 72 x 3 + 42

We consider the new divisor 72 and the new remainder 42,and apply the division lemma to get

72 = 42 x 1 + 30

We consider the new divisor 42 and the new remainder 30,and apply the division lemma to get

42 = 30 x 1 + 12

We consider the new divisor 30 and the new remainder 12,and apply the division lemma to get

30 = 12 x 2 + 6

We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get

12 = 6 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 330 and 918 is 6

Notice that 6 = HCF(12,6) = HCF(30,12) = HCF(42,30) = HCF(72,42) = HCF(258,72) = HCF(330,258) = HCF(918,330) .
