HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 385, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 162, 385, 75 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 162, 385, 75 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 162, 385, 75 is 1.

HCF(162, 385, 75) = 1

Highest common factor (HCF) of 162, 385, 75 is 1.

Highest Common Factor of 162,385,75 using Euclid's algorithm

Highest Common Factor of 162,385,75 is 1

Step 1: Since 385 > 162, we apply the division lemma to 385 and 162, to get

385 = 162 x 2 + 61

Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 61 and 162, to get

162 = 61 x 2 + 40

Step 3: We consider the new divisor 61 and the new remainder 40, and apply the division lemma to get

61 = 40 x 1 + 21

We consider the new divisor 40 and the new remainder 21,and apply the division lemma to get

40 = 21 x 1 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 162 and 385 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(61,40) = HCF(162,61) = HCF(385,162) .

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

Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get

75 = 1 x 75 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1

Notice that 1 = HCF(75,1) .
