HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 515, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 355, 515, 727 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 355, 515, 727 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 355, 515, 727 is 1.

HCF(355, 515, 727) = 1

Highest common factor (HCF) of 355, 515, 727 is 1.

Highest Common Factor of 355,515,727 using Euclid's algorithm

Highest Common Factor of 355,515,727 is 1

Step 1: Since 515 > 355, we apply the division lemma to 515 and 355, to get

515 = 355 x 1 + 160

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 160 and 355, to get

355 = 160 x 2 + 35

Step 3: We consider the new divisor 160 and the new remainder 35, and apply the division lemma to get

160 = 35 x 4 + 20

We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get

35 = 20 x 1 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 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 355 and 515 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(160,35) = HCF(355,160) = HCF(515,355) .

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

Step 1: Since 727 > 5, we apply the division lemma to 727 and 5, to get

727 = 5 x 145 + 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 727 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(727,5) .
