Given numbers are 771,438,321,910

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

The LCM of 771,438,321,910 is 5480275710.

Find LCM of 771,438,321,910 with Prime Factorization

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

2 x 3 x 257 x 73 x 107 x 455 = 5480275710

Therefore, the lowest common multiple of 771,438,321,910 is 5480275710.

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.

771 x 438 x 321 x 910 = 98644962780

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.

771 : 1, 3, 257, 771

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

321 : 1, 3, 107, 321

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,438,321,910, is 1.

Now, the common factors can be found like this.

771:3x 257

438:2x 3x 73

321:3x 107

910:2x 5x 7x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 98644962780/(1x18)

LCM = 98644962780/18

LCM = 5480275710

Thus, we can understand that the LCM of 771,438,321,910 is 5480275710.
