Given numbers are 350,668,992,780

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

The LCM of 350,668,992,780 is 1130656800.

Find LCM of 350,668,992,780 with Prime Factorization

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

2 x 2 x 5 x 35 x 167 x 248 x 39 = 1130656800

Therefore, the lowest common multiple of 350,668,992,780 is 1130656800.

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.

350 x 668 x 992 x 780 = 180905088000

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.

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

668 : 1, 2, 4, 167, 334, 668

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,668,992,780, is 2.

Now, the common factors can be found like this.

350:2x 5x 5x 7

668:2x 2x 167

992:2x 2x 2x 2x 2x 31

780:2x 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 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 180905088000/(2x80)

LCM = 180905088000/160

LCM = 1130656800

Thus, we can understand that the LCM of 350,668,992,780 is 1130656800.
