Given numbers are 273,428,974,245

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

The LCM of 273,428,974,245 is 1991605980.

Find LCM of 273,428,974,245 with Prime Factorization

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

2 x 7 x 39 x 214 x 487 x 35 = 1991605980

Therefore, the lowest common multiple of 273,428,974,245 is 1991605980.

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.

273 x 428 x 974 x 245 = 27882483720

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.

273 : 1, 3, 7, 13, 21, 39, 91, 273

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

974 : 1, 2, 487, 974

245 : 1, 5, 7, 35, 49, 245

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,428,974,245, is 1.

Now, the common factors can be found like this.

273:3x 7x 13

428:2x 2x 107

974:2x 487

245:5x 7x 7

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 27882483720/(1x14)

LCM = 27882483720/14

LCM = 1991605980

Thus, we can understand that the LCM of 273,428,974,245 is 1991605980.
