HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 575, 785, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 575, 785, 166 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 575, 785, 166 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 575, 785, 166 is 1.

HCF(575, 785, 166) = 1

HCF of 575, 785, 166 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 575, 785, 166 is 1.

Highest Common Factor of 575,785,166 using Euclid's algorithm

Highest Common Factor of 575,785,166 is 1

Step 1: Since 785 > 575, we apply the division lemma to 785 and 575, to get

785 = 575 x 1 + 210

Step 2: Since the reminder 575 ≠ 0, we apply division lemma to 210 and 575, to get

575 = 210 x 2 + 155

Step 3: We consider the new divisor 210 and the new remainder 155, and apply the division lemma to get

210 = 155 x 1 + 55

We consider the new divisor 155 and the new remainder 55,and apply the division lemma to get

155 = 55 x 2 + 45

We consider the new divisor 55 and the new remainder 45,and apply the division lemma to get

55 = 45 x 1 + 10

We consider the new divisor 45 and the new remainder 10,and apply the division lemma to get

45 = 10 x 4 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 575 and 785 is 5

Notice that 5 = HCF(10,5) = HCF(45,10) = HCF(55,45) = HCF(155,55) = HCF(210,155) = HCF(575,210) = HCF(785,575) .

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

Step 1: Since 166 > 5, we apply the division lemma to 166 and 5, to get

166 = 5 x 33 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 166 is 1

Notice that 1 = HCF(5,1) = HCF(166,5) .
