Given numbers are 770,634,720,321

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

The LCM of 770,634,720,321 is 1880469360.

Find LCM of 770,634,720,321 with Prime Factorization

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

2 x 3 x 5 x 77 x 317 x 24 x 107 = 1880469360

Therefore, the lowest common multiple of 770,634,720,321 is 1880469360.

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.

770 x 634 x 720 x 321 = 112828161600

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

634 : 1, 2, 317, 634

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,634,720,321, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

634:2x 317

720:2x 2x 2x 2x 3x 3x 5

321:3x 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 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 112828161600/(1x60)

LCM = 112828161600/60

LCM = 1880469360

Thus, we can understand that the LCM of 770,634,720,321 is 1880469360.
