HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 722, 297 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 273, 722, 297 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 273, 722, 297 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 273, 722, 297 is 1.

HCF(273, 722, 297) = 1

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

HCF of:

Highest common factor (HCF) of 273, 722, 297 is 1.

Highest Common Factor of 273,722,297 using Euclid's algorithm

Highest Common Factor of 273,722,297 is 1

Step 1: Since 722 > 273, we apply the division lemma to 722 and 273, to get

722 = 273 x 2 + 176

Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 176 and 273, to get

273 = 176 x 1 + 97

Step 3: We consider the new divisor 176 and the new remainder 97, and apply the division lemma to get

176 = 97 x 1 + 79

We consider the new divisor 97 and the new remainder 79,and apply the division lemma to get

97 = 79 x 1 + 18

We consider the new divisor 79 and the new remainder 18,and apply the division lemma to get

79 = 18 x 4 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 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 273 and 722 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(79,18) = HCF(97,79) = HCF(176,97) = HCF(273,176) = HCF(722,273) .

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

Step 1: Since 297 > 1, we apply the division lemma to 297 and 1, to get

297 = 1 x 297 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 297 is 1

Notice that 1 = HCF(297,1) .
