HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 405, 8920 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 405, 8920 is 5 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 405, 8920 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 405, 8920 is 5.

HCF(405, 8920) = 5

Highest common factor (HCF) of 405, 8920 is 5.

Highest Common Factor of 405,8920 using Euclid's algorithm

Highest Common Factor of 405,8920 is 5

Step 1: Since 8920 > 405, we apply the division lemma to 8920 and 405, to get

8920 = 405 x 22 + 10

Step 2: Since the reminder 405 ≠ 0, we apply division lemma to 10 and 405, to get

405 = 10 x 40 + 5

Step 3: We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 405 and 8920 is 5

Notice that 5 = HCF(10,5) = HCF(405,10) = HCF(8920,405) .
