Given numbers are 385,728,980,494,387

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

The LCM of 385,728,980,494,387 is 2060898840.

Find LCM of 385,728,980,494,387 with Prime Factorization

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

2 x 2 x 5 x 7 x 13 x 11 x 2 x 7 x 19 x 387 = 2060898840

Therefore, the lowest common multiple of 385,728,980,494,387 is 2060898840.

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.

385 x 728 x 980 x 494 x 387 = 52511702443200

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

494 : 1, 2, 13, 19, 26, 38, 247, 494

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,728,980,494,387, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

728:2x 2x 2x 7x 13

980:2x 2x 5x 7x 7

494:2x 13x 19

387:3x 3x 43

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 7x 7x 13 = 25480

Therefore, the value for common factors is 25480.

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 = 52511702443200/(1x25480)

LCM = 52511702443200/25480

LCM = 2060898840

Thus, we can understand that the LCM of 385,728,980,494,387 is 2060898840.
