Given numbers are 698,728,385,457,973

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

The LCM of 698,728,385,457,973 is 887667861080.

Find LCM of 698,728,385,457,973 with Prime Factorization

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

2 x 7 x 349 x 52 x 55 x 457 x 139 = 887667861080

Therefore, the lowest common multiple of 698,728,385,457,973 is 887667861080.

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.

698 x 728 x 385 x 457 x 973 = 86991450385840

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.

698 : 1, 2, 349, 698

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

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

457 : 1, 457

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,728,385,457,973, is 1.

Now, the common factors can be found like this.

698:2x 349

728:2x 2x 2x 7x 13

385:5x 7x 11

457:457

973:7x 139

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 86991450385840/(1x98)

LCM = 86991450385840/98

LCM = 887667861080

Thus, we can understand that the LCM of 698,728,385,457,973 is 887667861080.
