HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 817, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 817, 159 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, 817, 159 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, 817, 159 is 1.

HCF(485, 817, 159) = 1

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

HCF of:

Highest common factor (HCF) of 485, 817, 159 is 1.

Highest Common Factor of 485,817,159 using Euclid's algorithm

Highest Common Factor of 485,817,159 is 1

Step 1: Since 817 > 485, we apply the division lemma to 817 and 485, to get

817 = 485 x 1 + 332

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 332 and 485, to get

485 = 332 x 1 + 153

Step 3: We consider the new divisor 332 and the new remainder 153, and apply the division lemma to get

332 = 153 x 2 + 26

We consider the new divisor 153 and the new remainder 26,and apply the division lemma to get

153 = 26 x 5 + 23

We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get

26 = 23 x 1 + 3

We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get

23 = 3 x 7 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 817 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(153,26) = HCF(332,153) = HCF(485,332) = HCF(817,485) .

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

Step 1: Since 159 > 1, we apply the division lemma to 159 and 1, to get

159 = 1 x 159 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 159 is 1

Notice that 1 = HCF(159,1) .
