HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 854, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 854, 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 854, 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 854, 255 is 1.

HCF(854, 255) = 1

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

HCF of:

Highest common factor (HCF) of 854, 255 is 1.

Highest Common Factor of 854,255 using Euclid's algorithm

Highest Common Factor of 854,255 is 1

Step 1: Since 854 > 255, we apply the division lemma to 854 and 255, to get

854 = 255 x 3 + 89

Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 89 and 255, to get

255 = 89 x 2 + 77

Step 3: We consider the new divisor 89 and the new remainder 77, and apply the division lemma to get

89 = 77 x 1 + 12

We consider the new divisor 77 and the new remainder 12,and apply the division lemma to get

77 = 12 x 6 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 854 and 255 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(89,77) = HCF(255,89) = HCF(854,255) .
