HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 578, 305, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 578, 305, 390 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 578, 305, 390 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 578, 305, 390 is 1.

HCF(578, 305, 390) = 1

Highest common factor (HCF) of 578, 305, 390 is 1.

Highest Common Factor of 578,305,390 using Euclid's algorithm

Highest Common Factor of 578,305,390 is 1

Step 1: Since 578 > 305, we apply the division lemma to 578 and 305, to get

578 = 305 x 1 + 273

Step 2: Since the reminder 305 ≠ 0, we apply division lemma to 273 and 305, to get

305 = 273 x 1 + 32

Step 3: We consider the new divisor 273 and the new remainder 32, and apply the division lemma to get

273 = 32 x 8 + 17

We consider the new divisor 32 and the new remainder 17,and apply the division lemma to get

32 = 17 x 1 + 15

We consider the new divisor 17 and the new remainder 15,and apply the division lemma to get

17 = 15 x 1 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 578 and 305 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(32,17) = HCF(273,32) = HCF(305,273) = HCF(578,305) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get

390 = 1 x 390 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1

Notice that 1 = HCF(390,1) .
