Given numbers are 642,937,429,107,180

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

The LCM of 642,937,429,107,180 is 2580666660.

Find LCM of 642,937,429,107,180 with Prime Factorization

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

2 x 3 x 107 x 1 x 937 x 143 x 1 x 30 = 2580666660

Therefore, the lowest common multiple of 642,937,429,107,180 is 2580666660.

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.

642 x 937 x 429 x 107 x 180 = 4970363987160

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

937 : 1, 937

429 : 1, 3, 11, 13, 33, 39, 143, 429

107 : 1, 107

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,937,429,107,180, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

937:937

429:3x 11x 13

107:107

180:2x 2x 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 3x 3x 107 = 1926

Therefore, the value for common factors is 1926.

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 = 4970363987160/(1x1926)

LCM = 4970363987160/1926

LCM = 2580666660

Thus, we can understand that the LCM of 642,937,429,107,180 is 2580666660.
