HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 198, 984 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 144, 198, 984 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 144, 198, 984 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 144, 198, 984 is 6.

HCF(144, 198, 984) = 6

## HCF of 144, 198, 984 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 144, 198, 984 is 6. ### Highest Common Factor of 144,198,984 is 6

Step 1: Since 198 > 144, we apply the division lemma to 198 and 144, to get

198 = 144 x 1 + 54

Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 54 and 144, to get

144 = 54 x 2 + 36

Step 3: We consider the new divisor 54 and the new remainder 36, and apply the division lemma to get

54 = 36 x 1 + 18

We consider the new divisor 36 and the new remainder 18, and apply the division lemma to get

36 = 18 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 144 and 198 is 18

Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(144,54) = HCF(198,144) .

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

Step 1: Since 984 > 18, we apply the division lemma to 984 and 18, to get

984 = 18 x 54 + 12

Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 12 and 18, to get

18 = 12 x 1 + 6

Step 3: 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 18 and 984 is 6

Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(984,18) .
