HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 595, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 166, 595, 455 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 166, 595, 455 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 166, 595, 455 is 1.

HCF(166, 595, 455) = 1

HCF of 166, 595, 455 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 166, 595, 455 is 1.

Highest Common Factor of 166,595,455 using Euclid's algorithm

Highest Common Factor of 166,595,455 is 1

Step 1: Since 595 > 166, we apply the division lemma to 595 and 166, to get

595 = 166 x 3 + 97

Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 97 and 166, to get

166 = 97 x 1 + 69

Step 3: We consider the new divisor 97 and the new remainder 69, and apply the division lemma to get

97 = 69 x 1 + 28

We consider the new divisor 69 and the new remainder 28,and apply the division lemma to get

69 = 28 x 2 + 13

We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get

28 = 13 x 2 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 166 and 595 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(69,28) = HCF(97,69) = HCF(166,97) = HCF(595,166) .

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

Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get

455 = 1 x 455 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1

Notice that 1 = HCF(455,1) .
