HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 191, 102 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 454, 191, 102 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 454, 191, 102 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 454, 191, 102 is 1.

HCF(454, 191, 102) = 1

HCF of 454, 191, 102 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 454, 191, 102 is 1.

Highest Common Factor of 454,191,102 using Euclid's algorithm

Highest Common Factor of 454,191,102 is 1

Step 1: Since 454 > 191, we apply the division lemma to 454 and 191, to get

454 = 191 x 2 + 72

Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 72 and 191, to get

191 = 72 x 2 + 47

Step 3: We consider the new divisor 72 and the new remainder 47, and apply the division lemma to get

72 = 47 x 1 + 25

We consider the new divisor 47 and the new remainder 25,and apply the division lemma to get

47 = 25 x 1 + 22

We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get

25 = 22 x 1 + 3

We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get

22 = 3 x 7 + 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 454 and 191 is 1

Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(47,25) = HCF(72,47) = HCF(191,72) = HCF(454,191) .

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

Step 1: Since 102 > 1, we apply the division lemma to 102 and 1, to get

102 = 1 x 102 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 102 is 1

Notice that 1 = HCF(102,1) .
