Given numbers are 245,518,472,642

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

The LCM of 245,518,472,642 is 1373456280.

Find LCM of 245,518,472,642 with Prime Factorization

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

2 x 7 x 35 x 37 x 236 x 321 = 1373456280

Therefore, the lowest common multiple of 245,518,472,642 is 1373456280.

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.

245 x 518 x 472 x 642 = 38456775840

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.

245 : 1, 5, 7, 35, 49, 245

518 : 1, 2, 7, 14, 37, 74, 259, 518

472 : 1, 2, 4, 8, 59, 118, 236, 472

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,518,472,642, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

518:2x 7x 37

472:2x 2x 2x 59

642:2x 3x 107

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 7 = 28

Therefore, the value for common factors is 28.

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 = 38456775840/(1x28)

LCM = 38456775840/28

LCM = 1373456280

Thus, we can understand that the LCM of 245,518,472,642 is 1373456280.
