Given numbers are 780,921,912,219,497

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

The LCM of 780,921,912,219,497 is 660276467760.

Find LCM of 780,921,912,219,497 with Prime Factorization

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

2 x 2 x 3 x 65 x 307 x 76 x 73 x 497 = 660276467760

Therefore, the lowest common multiple of 780,921,912,219,497 is 660276467760.

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.

780 x 921 x 912 x 219 x 497 = 71309858518080

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

921 : 1, 3, 307, 921

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

219 : 1, 3, 73, 219

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,921,912,219,497, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

921:3x 307

912:2x 2x 2x 2x 3x 19

219:3x 73

497:7x 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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 71309858518080/(1x108)

LCM = 71309858518080/108

LCM = 660276467760

Thus, we can understand that the LCM of 780,921,912,219,497 is 660276467760.
