HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 505, 275 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 202, 505, 275 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 202, 505, 275 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 202, 505, 275 is 1.

HCF(202, 505, 275) = 1

Highest Common Factor of 202,505,275 using Euclid's algorithm

Highest Common Factor of 202,505,275 is 1

Step 1: Since 505 > 202, we apply the division lemma to 505 and 202, to get

505 = 202 x 2 + 101

Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 101 and 202, to get

202 = 101 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 101, the HCF of 202 and 505 is 101

Notice that 101 = HCF(202,101) = HCF(505,202) .

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

Step 1: Since 275 > 101, we apply the division lemma to 275 and 101, to get

275 = 101 x 2 + 73

Step 2: Since the reminder 101 ≠ 0, we apply division lemma to 73 and 101, to get

101 = 73 x 1 + 28

Step 3: We consider the new divisor 73 and the new remainder 28, and apply the division lemma to get

73 = 28 x 2 + 17

We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get

28 = 17 x 1 + 11

We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get

17 = 11 x 1 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 101 and 275 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(73,28) = HCF(101,73) = HCF(275,101) .
