HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 898, 272 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 898, 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 555, 898, 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 555, 898, 272 is 1.

HCF(555, 898, 272) = 1

Highest common factor (HCF) of 555, 898, 272 is 1.

Highest Common Factor of 555,898,272 using Euclid's algorithm

Highest Common Factor of 555,898,272 is 1

Step 1: Since 898 > 555, we apply the division lemma to 898 and 555, to get

898 = 555 x 1 + 343

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 343 and 555, to get

555 = 343 x 1 + 212

Step 3: We consider the new divisor 343 and the new remainder 212, and apply the division lemma to get

343 = 212 x 1 + 131

We consider the new divisor 212 and the new remainder 131,and apply the division lemma to get

212 = 131 x 1 + 81

We consider the new divisor 131 and the new remainder 81,and apply the division lemma to get

131 = 81 x 1 + 50

We consider the new divisor 81 and the new remainder 50,and apply the division lemma to get

81 = 50 x 1 + 31

We consider the new divisor 50 and the new remainder 31,and apply the division lemma to get

50 = 31 x 1 + 19

We consider the new divisor 31 and the new remainder 19,and apply the division lemma to get

31 = 19 x 1 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 555 and 898 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(31,19) = HCF(50,31) = HCF(81,50) = HCF(131,81) = HCF(212,131) = HCF(343,212) = HCF(555,343) = HCF(898,555) .

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) .
