Given numbers are 452,428,923,975,390

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

The LCM of 452,428,923,975,390 is 3347997900.

Find LCM of 452,428,923,975,390 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 113 x 107 x 71 x 1 x 5 = 3347997900

Therefore, the lowest common multiple of 452,428,923,975,390 is 3347997900.

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.

452 x 428 x 923 x 975 x 390 = 67897397412000

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.

452 : 1, 2, 4, 113, 226, 452

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

923 : 1, 13, 71, 923

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,428,923,975,390, is 1.

Now, the common factors can be found like this.

452:2x 2x 113

428:2x 2x 107

923:13x 71

975:3x 5x 5x 13

390:2x 3x 5x 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 3x 5x 13x 13 = 20280

Therefore, the value for common factors is 20280.

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 = 67897397412000/(1x20280)

LCM = 67897397412000/20280

LCM = 3347997900

Thus, we can understand that the LCM of 452,428,923,975,390 is 3347997900.
