Given numbers are 612,445,803,728

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

The LCM of 612,445,803,728 is 39801401640.

Find LCM of 612,445,803,728 with Prime Factorization

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

2 x 2 x 153 x 445 x 803 x 182 = 39801401640

Therefore, the lowest common multiple of 612,445,803,728 is 39801401640.

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.

612 x 445 x 803 x 728 = 159205606560

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

445 : 1, 5, 89, 445

803 : 1, 11, 73, 803

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 612,445,803,728, is 1.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

445:5x 89

803:11x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 159205606560/(1x4)

LCM = 159205606560/4

LCM = 39801401640

Thus, we can understand that the LCM of 612,445,803,728 is 39801401640.
