HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 627, 254 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 627, 254 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, 627, 254 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, 627, 254 is 1.

HCF(485, 627, 254) = 1

Highest common factor (HCF) of 485, 627, 254 is 1.

Highest Common Factor of 485,627,254 using Euclid's algorithm

Highest Common Factor of 485,627,254 is 1

Step 1: Since 627 > 485, we apply the division lemma to 627 and 485, to get

627 = 485 x 1 + 142

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 142 and 485, to get

485 = 142 x 3 + 59

Step 3: We consider the new divisor 142 and the new remainder 59, and apply the division lemma to get

142 = 59 x 2 + 24

We consider the new divisor 59 and the new remainder 24,and apply the division lemma to get

59 = 24 x 2 + 11

We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get

24 = 11 x 2 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

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 485 and 627 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(59,24) = HCF(142,59) = HCF(485,142) = HCF(627,485) .

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

Step 1: Since 254 > 1, we apply the division lemma to 254 and 1, to get

254 = 1 x 254 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 254 is 1

Notice that 1 = HCF(254,1) .
