HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 273, 302 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 745, 273, 302 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 745, 273, 302 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 745, 273, 302 is 1.

HCF(745, 273, 302) = 1

Highest common factor (HCF) of 745, 273, 302 is 1.

Highest Common Factor of 745,273,302 using Euclid's algorithm

Highest Common Factor of 745,273,302 is 1

Step 1: Since 745 > 273, we apply the division lemma to 745 and 273, to get

745 = 273 x 2 + 199

Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 199 and 273, to get

273 = 199 x 1 + 74

Step 3: We consider the new divisor 199 and the new remainder 74, and apply the division lemma to get

199 = 74 x 2 + 51

We consider the new divisor 74 and the new remainder 51,and apply the division lemma to get

74 = 51 x 1 + 23

We consider the new divisor 51 and the new remainder 23,and apply the division lemma to get

51 = 23 x 2 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 745 and 273 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(51,23) = HCF(74,51) = HCF(199,74) = HCF(273,199) = HCF(745,273) .

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

Step 1: Since 302 > 1, we apply the division lemma to 302 and 1, to get

302 = 1 x 302 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 302 is 1

Notice that 1 = HCF(302,1) .
