Given numbers are 690,950,558,390,915

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

The LCM of 690,950,558,390,915 is 4834246950.

Find LCM of 690,950,558,390,915 with Prime Factorization

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

2 x 3 x 5 x 23 x 95 x 93 x 13 x 61 = 4834246950

Therefore, the lowest common multiple of 690,950,558,390,915 is 4834246950.

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.

690 x 950 x 558 x 390 x 915 = 130524667650000

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,950,558,390,915, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

950:2x 5x 5x 19

558:2x 3x 3x 31

390:2x 3x 5x 13

915:3x 5x 61

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 3x 3x 3x 5x 5x 5 = 27000

Therefore, the value for common factors is 27000.

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 = 130524667650000/(1x27000)

LCM = 130524667650000/27000

LCM = 4834246950

Thus, we can understand that the LCM of 690,950,558,390,915 is 4834246950.
