Given numbers are 438,643,880,632

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

The LCM of 438,643,880,632 is 9789597840.

Find LCM of 438,643,880,632 with Prime Factorization

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

2 x 2 x 2 x 219 x 643 x 110 x 79 = 9789597840

Therefore, the lowest common multiple of 438,643,880,632 is 9789597840.

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.

438 x 643 x 880 x 632 = 156633565440

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.

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

643 : 1, 643

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

632 : 1, 2, 4, 8, 79, 158, 316, 632

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,643,880,632, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

643:643

880:2x 2x 2x 2x 5x 11

632:2x 2x 2x 79

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 2 = 16

Therefore, the value for common factors is 16.

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 = 156633565440/(1x16)

LCM = 156633565440/16

LCM = 9789597840

Thus, we can understand that the LCM of 438,643,880,632 is 9789597840.
