HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 365, 150, 258, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 365, 150, 258, 55 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 365, 150, 258, 55 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 365, 150, 258, 55 is 1.

HCF(365, 150, 258, 55) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 365, 150, 258, 55 is 1.

Highest Common Factor of 365,150,258,55 using Euclid's algorithm

Highest Common Factor of 365,150,258,55 is 1

Step 1: Since 365 > 150, we apply the division lemma to 365 and 150, to get

365 = 150 x 2 + 65

Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 65 and 150, to get

150 = 65 x 2 + 20

Step 3: We consider the new divisor 65 and the new remainder 20, and apply the division lemma to get

65 = 20 x 3 + 5

We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get

20 = 5 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 365 and 150 is 5

Notice that 5 = HCF(20,5) = HCF(65,20) = HCF(150,65) = HCF(365,150) .


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

Step 1: Since 258 > 5, we apply the division lemma to 258 and 5, to get

258 = 5 x 51 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: 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 5 and 258 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(258,5) .


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

Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get

55 = 1 x 55 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1

Notice that 1 = HCF(55,1) .
