Given numbers are 720,212,658,715,205

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

The LCM of 720,212,658,715,205 is 73607854320.

Find LCM of 720,212,658,715,205 with Prime Factorization

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

2 x 2 x 5 x 36 x 53 x 329 x 143 x 41 = 73607854320

Therefore, the lowest common multiple of 720,212,658,715,205 is 73607854320.

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.

720 x 212 x 658 x 715 x 205 = 14721570864000

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.

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

212 : 1, 2, 4, 53, 106, 212

658 : 1, 2, 7, 14, 47, 94, 329, 658

715 : 1, 5, 11, 13, 55, 65, 143, 715

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,212,658,715,205, is 1.

Now, the common factors can be found like this.

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

212:2x 2x 53

658:2x 7x 47

715:5x 11x 13

205:5x 41

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 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 14721570864000/(1x200)

LCM = 14721570864000/200

LCM = 73607854320

Thus, we can understand that the LCM of 720,212,658,715,205 is 73607854320.
