HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 504, 765, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 504, 765, 485 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 504, 765, 485 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 504, 765, 485 is 1.

HCF(504, 765, 485) = 1

Highest common factor (HCF) of 504, 765, 485 is 1.

Highest Common Factor of 504,765,485 using Euclid's algorithm

Highest Common Factor of 504,765,485 is 1

Step 1: Since 765 > 504, we apply the division lemma to 765 and 504, to get

765 = 504 x 1 + 261

Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 261 and 504, to get

504 = 261 x 1 + 243

Step 3: We consider the new divisor 261 and the new remainder 243, and apply the division lemma to get

261 = 243 x 1 + 18

We consider the new divisor 243 and the new remainder 18,and apply the division lemma to get

243 = 18 x 13 + 9

We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get

18 = 9 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 504 and 765 is 9

Notice that 9 = HCF(18,9) = HCF(243,18) = HCF(261,243) = HCF(504,261) = HCF(765,504) .

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

Step 1: Since 485 > 9, we apply the division lemma to 485 and 9, to get

485 = 9 x 53 + 8

Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 8 and 9, to get

9 = 8 x 1 + 1

Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 485 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(485,9) .
