HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 707, 578 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 390, 707, 578 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 390, 707, 578 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 390, 707, 578 is 1.

HCF(390, 707, 578) = 1

HCF of 390, 707, 578 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 390, 707, 578 is 1.

Highest Common Factor of 390,707,578 using Euclid's algorithm

Highest Common Factor of 390,707,578 is 1

Step 1: Since 707 > 390, we apply the division lemma to 707 and 390, to get

707 = 390 x 1 + 317

Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 317 and 390, to get

390 = 317 x 1 + 73

Step 3: We consider the new divisor 317 and the new remainder 73, and apply the division lemma to get

317 = 73 x 4 + 25

We consider the new divisor 73 and the new remainder 25,and apply the division lemma to get

73 = 25 x 2 + 23

We consider the new divisor 25 and the new remainder 23,and apply the division lemma to get

25 = 23 x 1 + 2

We consider the new divisor 23 and the new remainder 2,and apply the division lemma to get

23 = 2 x 11 + 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 390 and 707 is 1

Notice that 1 = HCF(2,1) = HCF(23,2) = HCF(25,23) = HCF(73,25) = HCF(317,73) = HCF(390,317) = HCF(707,390) .

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

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

578 = 1 x 578 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 578 is 1

Notice that 1 = HCF(578,1) .
