HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 280 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 398, 280 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 398, 280 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 398, 280 is 2.

HCF(398, 280) = 2

Highest common factor (HCF) of 398, 280 is 2.

Highest Common Factor of 398,280 using Euclid's algorithm

Highest Common Factor of 398,280 is 2

Step 1: Since 398 > 280, we apply the division lemma to 398 and 280, to get

398 = 280 x 1 + 118

Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 118 and 280, to get

280 = 118 x 2 + 44

Step 3: We consider the new divisor 118 and the new remainder 44, and apply the division lemma to get

118 = 44 x 2 + 30

We consider the new divisor 44 and the new remainder 30,and apply the division lemma to get

44 = 30 x 1 + 14

We consider the new divisor 30 and the new remainder 14,and apply the division lemma to get

30 = 14 x 2 + 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 398 and 280 is 2

Notice that 2 = HCF(14,2) = HCF(30,14) = HCF(44,30) = HCF(118,44) = HCF(280,118) = HCF(398,280) .
