HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 166, 275 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 432, 166, 275 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 432, 166, 275 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 432, 166, 275 is 1.

HCF(432, 166, 275) = 1

Highest common factor (HCF) of 432, 166, 275 is 1.

Highest Common Factor of 432,166,275 using Euclid's algorithm

Highest Common Factor of 432,166,275 is 1

Step 1: Since 432 > 166, we apply the division lemma to 432 and 166, to get

432 = 166 x 2 + 100

Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 100 and 166, to get

166 = 100 x 1 + 66

Step 3: We consider the new divisor 100 and the new remainder 66, and apply the division lemma to get

100 = 66 x 1 + 34

We consider the new divisor 66 and the new remainder 34,and apply the division lemma to get

66 = 34 x 1 + 32

We consider the new divisor 34 and the new remainder 32,and apply the division lemma to get

34 = 32 x 1 + 2

We consider the new divisor 32 and the new remainder 2,and apply the division lemma to get

32 = 2 x 16 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 432 and 166 is 2

Notice that 2 = HCF(32,2) = HCF(34,32) = HCF(66,34) = HCF(100,66) = HCF(166,100) = HCF(432,166) .

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

Step 1: Since 275 > 2, we apply the division lemma to 275 and 2, to get

275 = 2 x 137 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 275 is 1

Notice that 1 = HCF(2,1) = HCF(275,2) .
