HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 675, 432, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 675, 432, 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 675, 432, 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 675, 432, 368 is 1.

HCF(675, 432, 368) = 1

Highest common factor (HCF) of 675, 432, 368 is 1.

Highest Common Factor of 675,432,368 using Euclid's algorithm

Highest Common Factor of 675,432,368 is 1

Step 1: Since 675 > 432, we apply the division lemma to 675 and 432, to get

675 = 432 x 1 + 243

Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 243 and 432, to get

432 = 243 x 1 + 189

Step 3: We consider the new divisor 243 and the new remainder 189, and apply the division lemma to get

243 = 189 x 1 + 54

We consider the new divisor 189 and the new remainder 54,and apply the division lemma to get

189 = 54 x 3 + 27

We consider the new divisor 54 and the new remainder 27,and apply the division lemma to get

54 = 27 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 675 and 432 is 27

Notice that 27 = HCF(54,27) = HCF(189,54) = HCF(243,189) = HCF(432,243) = HCF(675,432) .

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

Step 1: Since 368 > 27, we apply the division lemma to 368 and 27, to get

368 = 27 x 13 + 17

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 17 and 27, to get

27 = 17 x 1 + 10

Step 3: We consider the new divisor 17 and the new remainder 10, and apply the division lemma to get

17 = 10 x 1 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 368 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(368,27) .
