Given numbers are 390,790,782,583,580

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

The LCM of 390,790,782,583,580 is 407347451940.

Find LCM of 390,790,782,583,580 with Prime Factorization

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

2 x 5 x 39 x 79 x 391 x 583 x 58 = 407347451940

Therefore, the lowest common multiple of 390,790,782,583,580 is 407347451940.

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.

390 x 790 x 782 x 583 x 580 = 81469490388000

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

790 : 1, 2, 5, 10, 79, 158, 395, 790

782 : 1, 2, 17, 23, 34, 46, 391, 782

583 : 1, 11, 53, 583

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,790,782,583,580, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

790:2x 5x 79

782:2x 17x 23

583:11x 53

580:2x 2x 5x 29

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 = 81469490388000/(1x200)

LCM = 81469490388000/200

LCM = 407347451940

Thus, we can understand that the LCM of 390,790,782,583,580 is 407347451940.
