HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 865, 537 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 865, 537 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, 865, 537 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, 865, 537 is 1.

HCF(555, 865, 537) = 1

Highest common factor (HCF) of 555, 865, 537 is 1.

Highest Common Factor of 555,865,537 using Euclid's algorithm

Highest Common Factor of 555,865,537 is 1

Step 1: Since 865 > 555, we apply the division lemma to 865 and 555, to get

865 = 555 x 1 + 310

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 310 and 555, to get

555 = 310 x 1 + 245

Step 3: We consider the new divisor 310 and the new remainder 245, and apply the division lemma to get

310 = 245 x 1 + 65

We consider the new divisor 245 and the new remainder 65,and apply the division lemma to get

245 = 65 x 3 + 50

We consider the new divisor 65 and the new remainder 50,and apply the division lemma to get

65 = 50 x 1 + 15

We consider the new divisor 50 and the new remainder 15,and apply the division lemma to get

50 = 15 x 3 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 555 and 865 is 5

Notice that 5 = HCF(15,5) = HCF(50,15) = HCF(65,50) = HCF(245,65) = HCF(310,245) = HCF(555,310) = HCF(865,555) .

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

Step 1: Since 537 > 5, we apply the division lemma to 537 and 5, to get

537 = 5 x 107 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 1

Step 3: 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 5 and 537 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(537,5) .
