HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 842, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 450, 842, 255 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 450, 842, 255 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 450, 842, 255 is 1.

HCF(450, 842, 255) = 1

Highest common factor (HCF) of 450, 842, 255 is 1.

Highest Common Factor of 450,842,255 using Euclid's algorithm

Highest Common Factor of 450,842,255 is 1

Step 1: Since 842 > 450, we apply the division lemma to 842 and 450, to get

842 = 450 x 1 + 392

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 392 and 450, to get

450 = 392 x 1 + 58

Step 3: We consider the new divisor 392 and the new remainder 58, and apply the division lemma to get

392 = 58 x 6 + 44

We consider the new divisor 58 and the new remainder 44,and apply the division lemma to get

58 = 44 x 1 + 14

We consider the new divisor 44 and the new remainder 14,and apply the division lemma to get

44 = 14 x 3 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 450 and 842 is 2

Notice that 2 = HCF(14,2) = HCF(44,14) = HCF(58,44) = HCF(392,58) = HCF(450,392) = HCF(842,450) .

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

Step 1: Since 255 > 2, we apply the division lemma to 255 and 2, to get

255 = 2 x 127 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 255 is 1

Notice that 1 = HCF(2,1) = HCF(255,2) .
