Given numbers are 638,510,738,438,669

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

The LCM of 638,510,738,438,669 is 325756952730.

Find LCM of 638,510,738,438,669 with Prime Factorization

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

2 x 3 x 319 x 85 x 123 x 73 x 223 = 325756952730

Therefore, the lowest common multiple of 638,510,738,438,669 is 325756952730.

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.

638 x 510 x 738 x 438 x 669 = 70363501789680

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

438 : 1, 2, 3, 6, 73, 146, 219, 438

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,510,738,438,669, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

510:2x 3x 5x 17

738:2x 3x 3x 41

438:2x 3x 73

669:3x 223

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 3 = 216

Therefore, the value for common factors is 216.

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 = 70363501789680/(1x216)

LCM = 70363501789680/216

LCM = 325756952730

Thus, we can understand that the LCM of 638,510,738,438,669 is 325756952730.
