HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 325, 198, 224 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 325, 198, 224 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 325, 198, 224 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 325, 198, 224 is 1.

HCF(325, 198, 224) = 1

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

HCF of:

Highest common factor (HCF) of 325, 198, 224 is 1.

Highest Common Factor of 325,198,224 using Euclid's algorithm

Highest Common Factor of 325,198,224 is 1

Step 1: Since 325 > 198, we apply the division lemma to 325 and 198, to get

325 = 198 x 1 + 127

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 127 and 198, to get

198 = 127 x 1 + 71

Step 3: We consider the new divisor 127 and the new remainder 71, and apply the division lemma to get

127 = 71 x 1 + 56

We consider the new divisor 71 and the new remainder 56,and apply the division lemma to get

71 = 56 x 1 + 15

We consider the new divisor 56 and the new remainder 15,and apply the division lemma to get

56 = 15 x 3 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 325 and 198 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(56,15) = HCF(71,56) = HCF(127,71) = HCF(198,127) = HCF(325,198) .

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

Step 1: Since 224 > 1, we apply the division lemma to 224 and 1, to get

224 = 1 x 224 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 224 is 1

Notice that 1 = HCF(224,1) .
