HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 982, 245 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 253, 982, 245 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 253, 982, 245 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 253, 982, 245 is 1.

HCF(253, 982, 245) = 1

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

HCF of:

Highest common factor (HCF) of 253, 982, 245 is 1.

Highest Common Factor of 253,982,245 using Euclid's algorithm

Highest Common Factor of 253,982,245 is 1

Step 1: Since 982 > 253, we apply the division lemma to 982 and 253, to get

982 = 253 x 3 + 223

Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 223 and 253, to get

253 = 223 x 1 + 30

Step 3: We consider the new divisor 223 and the new remainder 30, and apply the division lemma to get

223 = 30 x 7 + 13

We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get

30 = 13 x 2 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 253 and 982 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(223,30) = HCF(253,223) = HCF(982,253) .

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

Step 1: Since 245 > 1, we apply the division lemma to 245 and 1, to get

245 = 1 x 245 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 245 is 1

Notice that 1 = HCF(245,1) .
