Given numbers are 774,898,688,391

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

The LCM of 774,898,688,391 is 1087061328.

Find LCM of 774,898,688,391 with Prime Factorization

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

2 x 43 x 9 x 449 x 8 x 391 = 1087061328

Therefore, the lowest common multiple of 774,898,688,391 is 1087061328.

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.

774 x 898 x 688 x 391 = 186974548416

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

898 : 1, 2, 449, 898

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,898,688,391, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

898:2x 449

688:2x 2x 2x 2x 43

391:17x 23

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 43 = 172

Therefore, the value for common factors is 172.

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 = 186974548416/(1x172)

LCM = 186974548416/172

LCM = 1087061328

Thus, we can understand that the LCM of 774,898,688,391 is 1087061328.
