Given numbers are 998,719,272,146,728

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

The LCM of 998,719,272,146,728 is 648279953776.

Find LCM of 998,719,272,146,728 with Prime Factorization

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

2 x 2 x 2 x 499 x 719 x 34 x 73 x 91 = 648279953776

Therefore, the lowest common multiple of 998,719,272,146,728 is 648279953776.

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.

998 x 719 x 272 x 146 x 728 = 20744958520832

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.

998 : 1, 2, 499, 998

719 : 1, 719

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

146 : 1, 2, 73, 146

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,719,272,146,728, is 1.

Now, the common factors can be found like this.

998:2x 499

719:719

272:2x 2x 2x 2x 17

146:2x 73

728:2x 2x 2x 7x 13

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 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 20744958520832/(1x32)

LCM = 20744958520832/32

LCM = 648279953776

Thus, we can understand that the LCM of 998,719,272,146,728 is 648279953776.
