Given numbers are 422,247,915,702,816

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

The LCM of 422,247,915,702,816 is 116737910640.

Find LCM of 422,247,915,702,816 with Prime Factorization

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

2 x 3 x 13 x 211 x 19 x 305 x 9 x 136 = 116737910640

Therefore, the lowest common multiple of 422,247,915,702,816 is 116737910640.

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.

422 x 247 x 915 x 702 x 816 = 54633342179520

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.

422 : 1, 2, 211, 422

247 : 1, 13, 19, 247

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,247,915,702,816, is 1.

Now, the common factors can be found like this.

422:2x 211

247:13x 19

915:3x 5x 61

702:2x 3x 3x 3x 13

816:2x 2x 2x 2x 3x 17

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 3x 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 54633342179520/(1x468)

LCM = 54633342179520/468

LCM = 116737910640

Thus, we can understand that the LCM of 422,247,915,702,816 is 116737910640.
