Given numbers are 877,812,355,128,781

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

The LCM of 877,812,355,128,781 is 88987015040.

Find LCM of 877,812,355,128,781 with Prime Factorization

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

2 x 2 x 71 x 877 x 203 x 5 x 32 x 11 = 88987015040

Therefore, the lowest common multiple of 877,812,355,128,781 is 88987015040.

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.

877 x 812 x 355 x 128 x 781 = 25272312271360

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.

877 : 1, 877

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

355 : 1, 5, 71, 355

128 : 1, 2, 4, 8, 16, 32, 64, 128

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 877,812,355,128,781, is 1.

Now, the common factors can be found like this.

877:877

812:2x 2x 7x 29

355:5x 71

128:2x 2x 2x 2x 2x 2x 2

781:11x 71

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 71 = 284

Therefore, the value for common factors is 284.

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 = 25272312271360/(1x284)

LCM = 25272312271360/284

LCM = 88987015040

Thus, we can understand that the LCM of 877,812,355,128,781 is 88987015040.
