HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 289, 272 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 505, 289, 272 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 505, 289, 272 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 505, 289, 272 is 1.

HCF(505, 289, 272) = 1

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

HCF of:

Highest common factor (HCF) of 505, 289, 272 is 1.

Highest Common Factor of 505,289,272 using Euclid's algorithm

Highest Common Factor of 505,289,272 is 1

Step 1: Since 505 > 289, we apply the division lemma to 505 and 289, to get

505 = 289 x 1 + 216

Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 216 and 289, to get

289 = 216 x 1 + 73

Step 3: We consider the new divisor 216 and the new remainder 73, and apply the division lemma to get

216 = 73 x 2 + 70

We consider the new divisor 73 and the new remainder 70,and apply the division lemma to get

73 = 70 x 1 + 3

We consider the new divisor 70 and the new remainder 3,and apply the division lemma to get

70 = 3 x 23 + 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 505 and 289 is 1

Notice that 1 = HCF(3,1) = HCF(70,3) = HCF(73,70) = HCF(216,73) = HCF(289,216) = HCF(505,289) .

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

Step 1: Since 272 > 1, we apply the division lemma to 272 and 1, to get

272 = 1 x 272 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 272 is 1

Notice that 1 = HCF(272,1) .
