Given numbers are 142,428,102,745

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

The LCM of 142,428,102,745 is 1154592060.

Find LCM of 142,428,102,745 with Prime Factorization

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

2 x 71 x 214 x 51 x 745 = 1154592060

Therefore, the lowest common multiple of 142,428,102,745 is 1154592060.

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.

142 x 428 x 102 x 745 = 4618368240

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.

142 : 1, 2, 71, 142

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

102 : 1, 2, 3, 6, 17, 34, 51, 102

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,428,102,745, is 1.

Now, the common factors can be found like this.

142:2x 71

428:2x 2x 107

102:2x 3x 17

745:5x 149

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4618368240/(1x4)

LCM = 4618368240/4

LCM = 1154592060

Thus, we can understand that the LCM of 142,428,102,745 is 1154592060.
