HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 975, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 406, 975, 189 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 406, 975, 189 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 406, 975, 189 is 1.

HCF(406, 975, 189) = 1

HCF of 406, 975, 189 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 406, 975, 189 is 1.

Highest Common Factor of 406,975,189 using Euclid's algorithm

Highest Common Factor of 406,975,189 is 1

Step 1: Since 975 > 406, we apply the division lemma to 975 and 406, to get

975 = 406 x 2 + 163

Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 163 and 406, to get

406 = 163 x 2 + 80

Step 3: We consider the new divisor 163 and the new remainder 80, and apply the division lemma to get

163 = 80 x 2 + 3

We consider the new divisor 80 and the new remainder 3,and apply the division lemma to get

80 = 3 x 26 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 406 and 975 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(80,3) = HCF(163,80) = HCF(406,163) = HCF(975,406) .

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

Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get

189 = 1 x 189 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1

Notice that 1 = HCF(189,1) .
