HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 150, 805, 723 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 150, 805, 723 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 150, 805, 723 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 150, 805, 723 is 1.

HCF(150, 805, 723) = 1

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

HCF of:

Highest common factor (HCF) of 150, 805, 723 is 1.

Highest Common Factor of 150,805,723 using Euclid's algorithm

Highest Common Factor of 150,805,723 is 1

Step 1: Since 805 > 150, we apply the division lemma to 805 and 150, to get

805 = 150 x 5 + 55

Step 2: Since the reminder 150 ≠ 0, we apply division lemma to 55 and 150, to get

150 = 55 x 2 + 40

Step 3: We consider the new divisor 55 and the new remainder 40, and apply the division lemma to get

55 = 40 x 1 + 15

We consider the new divisor 40 and the new remainder 15,and apply the division lemma to get

40 = 15 x 2 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 150 and 805 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(40,15) = HCF(55,40) = HCF(150,55) = HCF(805,150) .

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

Step 1: Since 723 > 5, we apply the division lemma to 723 and 5, to get

723 = 5 x 144 + 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 723 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(723,5) .
