Given numbers are 428,560,869,135

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

The LCM of 428,560,869,135 is 1405902960.

Find LCM of 428,560,869,135 with Prime Factorization

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

2 x 2 x 5 x 107 x 28 x 869 x 27 = 1405902960

Therefore, the lowest common multiple of 428,560,869,135 is 1405902960.

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.

428 x 560 x 869 x 135 = 28118059200

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.

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

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

869 : 1, 11, 79, 869

135 : 1, 3, 5, 9, 15, 27, 45, 135

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,560,869,135, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

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

869:11x 79

135:3x 3x 3x 5

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 5 = 20

Therefore, the value for common factors is 20.

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 = 28118059200/(1x20)

LCM = 28118059200/20

LCM = 1405902960

Thus, we can understand that the LCM of 428,560,869,135 is 1405902960.
