Given numbers are 530,106,440,720

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 530,106,440,720 is 419760.

Find LCM of 530,106,440,720 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 5 x 53 x 1 x 1 x 11 x 18 = 419760

Therefore, the lowest common multiple of 530,106,440,720 is 419760.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

530 x 106 x 440 x 720 = 17797824000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

530 : 1, 2, 5, 10, 53, 106, 265, 530

106 : 1, 2, 53, 106

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,106,440,720, is 2.

Now, the common factors can be found like this.

530:2x 5x 53

106:2x 53

440:2x 2x 2x 5x 11

720:2x 2x 2x 2x 3x 3x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 5x 5x 53 = 21200

Therefore, the value for common factors is 21200.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 17797824000/(2x21200)

LCM = 17797824000/42400

LCM = 419760

Thus, we can understand that the LCM of 530,106,440,720 is 419760.
