HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 548, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 548, 57 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 485, 548, 57 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 485, 548, 57 is 1.

HCF(485, 548, 57) = 1

Highest common factor (HCF) of 485, 548, 57 is 1.

Highest Common Factor of 485,548,57 using Euclid's algorithm

Highest Common Factor of 485,548,57 is 1

Step 1: Since 548 > 485, we apply the division lemma to 548 and 485, to get

548 = 485 x 1 + 63

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 63 and 485, to get

485 = 63 x 7 + 44

Step 3: We consider the new divisor 63 and the new remainder 44, and apply the division lemma to get

63 = 44 x 1 + 19

We consider the new divisor 44 and the new remainder 19,and apply the division lemma to get

44 = 19 x 2 + 6

We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get

19 = 6 x 3 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 485 and 548 is 1

Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(44,19) = HCF(63,44) = HCF(485,63) = HCF(548,485) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
