HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 773, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 170, 773, 382 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 170, 773, 382 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 170, 773, 382 is 1.

HCF(170, 773, 382) = 1

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

HCF of:

Highest common factor (HCF) of 170, 773, 382 is 1.

Highest Common Factor of 170,773,382 using Euclid's algorithm

Highest Common Factor of 170,773,382 is 1

Step 1: Since 773 > 170, we apply the division lemma to 773 and 170, to get

773 = 170 x 4 + 93

Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 93 and 170, to get

170 = 93 x 1 + 77

Step 3: We consider the new divisor 93 and the new remainder 77, and apply the division lemma to get

93 = 77 x 1 + 16

We consider the new divisor 77 and the new remainder 16,and apply the division lemma to get

77 = 16 x 4 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

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

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 170 and 773 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(77,16) = HCF(93,77) = HCF(170,93) = HCF(773,170) .

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

Step 1: Since 382 > 1, we apply the division lemma to 382 and 1, to get

382 = 1 x 382 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 382 is 1

Notice that 1 = HCF(382,1) .
