Given numbers are 938,669,344,440,428

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

The LCM of 938,669,344,440,428 is 635190318840.

Find LCM of 938,669,344,440,428 with Prime Factorization

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

2 x 2 x 2 x 469 x 669 x 43 x 55 x 107 = 635190318840

Therefore, the lowest common multiple of 938,669,344,440,428 is 635190318840.

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.

938 x 669 x 344 x 440 x 428 = 40652180405760

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

669 : 1, 3, 223, 669

344 : 1, 2, 4, 8, 43, 86, 172, 344

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,669,344,440,428, is 1.

Now, the common factors can be found like this.

938:2x 7x 67

669:3x 223

344:2x 2x 2x 43

440:2x 2x 2x 5x 11

428:2x 2x 107

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 40652180405760/(1x64)

LCM = 40652180405760/64

LCM = 635190318840

Thus, we can understand that the LCM of 938,669,344,440,428 is 635190318840.
