HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 919, 480 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 919, 480 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 919, 480 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 919, 480 is 1.

HCF(919, 480) = 1

Highest common factor (HCF) of 919, 480 is 1.

Highest Common Factor of 919,480 using Euclid's algorithm

Highest Common Factor of 919,480 is 1

Step 1: Since 919 > 480, we apply the division lemma to 919 and 480, to get

919 = 480 x 1 + 439

Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 439 and 480, to get

480 = 439 x 1 + 41

Step 3: We consider the new divisor 439 and the new remainder 41, and apply the division lemma to get

439 = 41 x 10 + 29

We consider the new divisor 41 and the new remainder 29,and apply the division lemma to get

41 = 29 x 1 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 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 919 and 480 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(41,29) = HCF(439,41) = HCF(480,439) = HCF(919,480) .
