Given numbers are 788,428,478,355

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

The LCM of 788,428,478,355 is 7153791020.

Find LCM of 788,428,478,355 with Prime Factorization

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

2 x 2 x 197 x 107 x 239 x 355 = 7153791020

Therefore, the lowest common multiple of 788,428,478,355 is 7153791020.

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.

788 x 428 x 478 x 355 = 57230328160

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.

788 : 1, 2, 4, 197, 394, 788

428 : 1, 2, 4, 107, 214, 428

478 : 1, 2, 239, 478

355 : 1, 5, 71, 355

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,428,478,355, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

428:2x 2x 107

478:2x 239

355:5x 71

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 2 = 8

Therefore, the value for common factors is 8.

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 = 57230328160/(1x8)

LCM = 57230328160/8

LCM = 7153791020

Thus, we can understand that the LCM of 788,428,478,355 is 7153791020.
