Given numbers are 434,349,732,156,728

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

The LCM of 434,349,732,156,728 is 1441350456.

Find LCM of 434,349,732,156,728 with Prime Factorization

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

2 x 2 x 3 x 7 x 13 x 31 x 349 x 61 x 1 x 2 = 1441350456

Therefore, the lowest common multiple of 434,349,732,156,728 is 1441350456.

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.

434 x 349 x 732 x 156 x 728 = 12591637583616

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

349 : 1, 349

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

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 434,349,732,156,728, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

349:349

732:2x 2x 3x 61

156:2x 2x 3x 13

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 2x 3x 7x 13 = 8736

Therefore, the value for common factors is 8736.

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 = 12591637583616/(1x8736)

LCM = 12591637583616/8736

LCM = 1441350456

Thus, we can understand that the LCM of 434,349,732,156,728 is 1441350456.
