HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 308, 399 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 570, 308, 399 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 570, 308, 399 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 570, 308, 399 is 1.

HCF(570, 308, 399) = 1

Highest Common Factor of 570,308,399 using Euclid's algorithm

Highest Common Factor of 570,308,399 is 1

Step 1: Since 570 > 308, we apply the division lemma to 570 and 308, to get

570 = 308 x 1 + 262

Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 262 and 308, to get

308 = 262 x 1 + 46

Step 3: We consider the new divisor 262 and the new remainder 46, and apply the division lemma to get

262 = 46 x 5 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 570 and 308 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(262,46) = HCF(308,262) = HCF(570,308) .

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

Step 1: Since 399 > 2, we apply the division lemma to 399 and 2, to get

399 = 2 x 199 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 399 is 1

Notice that 1 = HCF(2,1) = HCF(399,2) .
