Given numbers are 128,442,560,357

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

The LCM of 128,442,560,357 is 2970240.

Find LCM of 128,442,560,357 with Prime Factorization

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

2 x 2 x 2 x 2 x 7 x 17 x 8 x 13 x 5 x 3 = 2970240

Therefore, the lowest common multiple of 128,442,560,357 is 2970240.

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.

128 x 442 x 560 x 357 = 11310673920

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

442 : 1, 2, 13, 17, 26, 34, 221, 442

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,442,560,357, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

442:2x 13x 17

560:2x 2x 2x 2x 5x 7

357:3x 7x 17

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 2x 2x 7x 17 = 3808

Therefore, the value for common factors is 3808.

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 = 11310673920/(1x3808)

LCM = 11310673920/3808

LCM = 2970240

Thus, we can understand that the LCM of 128,442,560,357 is 2970240.
