HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 173, 275, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 173, 275, 785 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 173, 275, 785 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 173, 275, 785 is 1.

HCF(173, 275, 785) = 1

Highest common factor (HCF) of 173, 275, 785 is 1.

Highest Common Factor of 173,275,785 using Euclid's algorithm

Highest Common Factor of 173,275,785 is 1

Step 1: Since 275 > 173, we apply the division lemma to 275 and 173, to get

275 = 173 x 1 + 102

Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 102 and 173, to get

173 = 102 x 1 + 71

Step 3: We consider the new divisor 102 and the new remainder 71, and apply the division lemma to get

102 = 71 x 1 + 31

We consider the new divisor 71 and the new remainder 31,and apply the division lemma to get

71 = 31 x 2 + 9

We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get

31 = 9 x 3 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 173 and 275 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(71,31) = HCF(102,71) = HCF(173,102) = HCF(275,173) .

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

Step 1: Since 785 > 1, we apply the division lemma to 785 and 1, to get

785 = 1 x 785 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 785 is 1

Notice that 1 = HCF(785,1) .
