HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 508, 150 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 787, 508, 150 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 787, 508, 150 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 787, 508, 150 is 1.

HCF(787, 508, 150) = 1

Highest common factor (HCF) of 787, 508, 150 is 1.

Highest Common Factor of 787,508,150 using Euclid's algorithm

Highest Common Factor of 787,508,150 is 1

Step 1: Since 787 > 508, we apply the division lemma to 787 and 508, to get

787 = 508 x 1 + 279

Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 279 and 508, to get

508 = 279 x 1 + 229

Step 3: We consider the new divisor 279 and the new remainder 229, and apply the division lemma to get

279 = 229 x 1 + 50

We consider the new divisor 229 and the new remainder 50,and apply the division lemma to get

229 = 50 x 4 + 29

We consider the new divisor 50 and the new remainder 29,and apply the division lemma to get

50 = 29 x 1 + 21

We consider the new divisor 29 and the new remainder 21,and apply the division lemma to get

29 = 21 x 1 + 8

We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get

21 = 8 x 2 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 787 and 508 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(29,21) = HCF(50,29) = HCF(229,50) = HCF(279,229) = HCF(508,279) = HCF(787,508) .

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

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

150 = 1 x 150 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 150 is 1

Notice that 1 = HCF(150,1) .
