Given numbers are 290,406,641,318

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

The LCM of 290,406,641,318 is 206895570.

Find LCM of 290,406,641,318 with Prime Factorization

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

2 x 29 x 5 x 7 x 641 x 159 = 206895570

Therefore, the lowest common multiple of 290,406,641,318 is 206895570.

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.

290 x 406 x 641 x 318 = 23999886120

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

406 : 1, 2, 7, 14, 29, 58, 203, 406

641 : 1, 641

318 : 1, 2, 3, 6, 53, 106, 159, 318

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,406,641,318, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

406:2x 7x 29

641:641

318:2x 3x 53

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 29 = 116

Therefore, the value for common factors is 116.

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 = 23999886120/(1x116)

LCM = 23999886120/116

LCM = 206895570

Thus, we can understand that the LCM of 290,406,641,318 is 206895570.
