# Highest Common Factor of 30, 48, 60, 66 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 48, 60, 66 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 30, 48, 60, 66 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 30, 48, 60, 66 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 30, 48, 60, 66 is 6.

HCF(30, 48, 60, 66) = 6

## HCF of 30, 48, 60, 66 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 30, 48, 60, 66 is 6.

### Highest Common Factor of 30,48,60,66 using Euclid's algorithm

Step 1: Since 48 > 30, we apply the division lemma to 48 and 30, to get

48 = 30 x 1 + 18

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 18 and 30, to get

30 = 18 x 1 + 12

Step 3: We consider the new divisor 18 and the new remainder 12, and apply the division lemma to get

18 = 12 x 1 + 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 30 and 48 is 6

Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(48,30) .

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

Step 1: Since 60 > 6, we apply the division lemma to 60 and 6, to get

60 = 6 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 60 is 6

Notice that 6 = HCF(60,6) .

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

Step 1: Since 66 > 6, we apply the division lemma to 66 and 6, to get

66 = 6 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 66 is 6

Notice that 6 = HCF(66,6) .
