Given numbers are 670,642,509,387

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

The LCM of 670,642,509,387 is 14121711270.

Find LCM of 670,642,509,387 with Prime Factorization

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

2 x 3 x 335 x 107 x 509 x 129 = 14121711270

Therefore, the lowest common multiple of 670,642,509,387 is 14121711270.

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.

670 x 642 x 509 x 387 = 84730267620

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

642 : 1, 2, 3, 6, 107, 214, 321, 642

509 : 1, 509

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 670,642,509,387, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

642:2x 3x 107

509:509

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 3 = 6

Therefore, the value for common factors is 6.

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 = 84730267620/(1x6)

LCM = 84730267620/6

LCM = 14121711270

Thus, we can understand that the LCM of 670,642,509,387 is 14121711270.
