HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 280, 818 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 280, 818 is 2 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 280, 818 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 280, 818 is 2.

HCF(280, 818) = 2

Highest common factor (HCF) of 280, 818 is 2.

Highest Common Factor of 280,818 using Euclid's algorithm

Highest Common Factor of 280,818 is 2

Step 1: Since 818 > 280, we apply the division lemma to 818 and 280, to get

818 = 280 x 2 + 258

Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 258 and 280, to get

280 = 258 x 1 + 22

Step 3: We consider the new divisor 258 and the new remainder 22, and apply the division lemma to get

258 = 22 x 11 + 16

We consider the new divisor 22 and the new remainder 16,and apply the division lemma to get

22 = 16 x 1 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 280 and 818 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(22,16) = HCF(258,22) = HCF(280,258) = HCF(818,280) .
