HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 727, 918 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 455, 727, 918 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 455, 727, 918 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 455, 727, 918 is 1.

HCF(455, 727, 918) = 1

HCF of 455, 727, 918 using Euclid's algorithm

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

Highest common factor (HCF) of 455, 727, 918 is 1.

Highest Common Factor of 455,727,918 using Euclid's algorithm

Highest Common Factor of 455,727,918 is 1

Step 1: Since 727 > 455, we apply the division lemma to 727 and 455, to get

727 = 455 x 1 + 272

Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 272 and 455, to get

455 = 272 x 1 + 183

Step 3: We consider the new divisor 272 and the new remainder 183, and apply the division lemma to get

272 = 183 x 1 + 89

We consider the new divisor 183 and the new remainder 89,and apply the division lemma to get

183 = 89 x 2 + 5

We consider the new divisor 89 and the new remainder 5,and apply the division lemma to get

89 = 5 x 17 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 455 and 727 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(89,5) = HCF(183,89) = HCF(272,183) = HCF(455,272) = HCF(727,455) .

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

Step 1: Since 918 > 1, we apply the division lemma to 918 and 1, to get

918 = 1 x 918 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 918 is 1

Notice that 1 = HCF(918,1) .
