Given numbers are 786,815,578,245

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

The LCM of 786,815,578,245 is 9071394990.

Find LCM of 786,815,578,245 with Prime Factorization

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

2 x 5 x 393 x 163 x 289 x 49 = 9071394990

Therefore, the lowest common multiple of 786,815,578,245 is 9071394990.

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.

786 x 815 x 578 x 245 = 90713949900

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

815 : 1, 5, 163, 815

578 : 1, 2, 17, 34, 289, 578

245 : 1, 5, 7, 35, 49, 245

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,815,578,245, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

815:5x 163

578:2x 17x 17

245:5x 7x 7

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 90713949900/(1x10)

LCM = 90713949900/10

LCM = 9071394990

Thus, we can understand that the LCM of 786,815,578,245 is 9071394990.
