HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 579, 74515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 579, 74515 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 579, 74515 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 579, 74515 is 1.

HCF(579, 74515) = 1

Highest common factor (HCF) of 579, 74515 is 1.

Highest Common Factor of 579,74515 using Euclid's algorithm

Highest Common Factor of 579,74515 is 1

Step 1: Since 74515 > 579, we apply the division lemma to 74515 and 579, to get

74515 = 579 x 128 + 403

Step 2: Since the reminder 579 ≠ 0, we apply division lemma to 403 and 579, to get

579 = 403 x 1 + 176

Step 3: We consider the new divisor 403 and the new remainder 176, and apply the division lemma to get

403 = 176 x 2 + 51

We consider the new divisor 176 and the new remainder 51,and apply the division lemma to get

176 = 51 x 3 + 23

We consider the new divisor 51 and the new remainder 23,and apply the division lemma to get

51 = 23 x 2 + 5

We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get

23 = 5 x 4 + 3

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

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 579 and 74515 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(51,23) = HCF(176,51) = HCF(403,176) = HCF(579,403) = HCF(74515,579) .
