Given numbers are 305,749,897,428

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

The LCM of 305,749,897,428 is 819660660.

Find LCM of 305,749,897,428 with Prime Factorization

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

107 x 305 x 7 x 897 x 4 = 819660660

Therefore, the lowest common multiple of 305,749,897,428 is 819660660.

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.

305 x 749 x 897 x 428 = 87703690620

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.

305 : 1, 5, 61, 305

749 : 1, 7, 107, 749

897 : 1, 3, 13, 23, 39, 69, 299, 897

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,749,897,428, is 1.

Now, the common factors can be found like this.

305:5x 61

749:7x 107

897:3x 13x 23

428:2x 2x 107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 87703690620/(1x107)

LCM = 87703690620/107

LCM = 819660660

Thus, we can understand that the LCM of 305,749,897,428 is 819660660.
