HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 346, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 189, 346, 368 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 189, 346, 368 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 189, 346, 368 is 1.

HCF(189, 346, 368) = 1

HCF of 189, 346, 368 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 189, 346, 368 is 1.

Highest Common Factor of 189,346,368 using Euclid's algorithm

Highest Common Factor of 189,346,368 is 1

Step 1: Since 346 > 189, we apply the division lemma to 346 and 189, to get

346 = 189 x 1 + 157

Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 157 and 189, to get

189 = 157 x 1 + 32

Step 3: We consider the new divisor 157 and the new remainder 32, and apply the division lemma to get

157 = 32 x 4 + 29

We consider the new divisor 32 and the new remainder 29,and apply the division lemma to get

32 = 29 x 1 + 3

We consider the new divisor 29 and the new remainder 3,and apply the division lemma to get

29 = 3 x 9 + 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 189 and 346 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(29,3) = HCF(32,29) = HCF(157,32) = HCF(189,157) = HCF(346,189) .

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

Step 1: Since 368 > 1, we apply the division lemma to 368 and 1, to get

368 = 1 x 368 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 368 is 1

Notice that 1 = HCF(368,1) .
