Given numbers are 660,278,623,380

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

The LCM of 660,278,623,380 is 1085926380.

Find LCM of 660,278,623,380 with Prime Factorization

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

2 x 2 x 5 x 33 x 139 x 623 x 19 = 1085926380

Therefore, the lowest common multiple of 660,278,623,380 is 1085926380.

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.

660 x 278 x 623 x 380 = 43437055200

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

278 : 1, 2, 139, 278

623 : 1, 7, 89, 623

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,278,623,380, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

278:2x 139

623:7x 89

380:2x 2x 5x 19

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 43437055200/(1x40)

LCM = 43437055200/40

LCM = 1085926380

Thus, we can understand that the LCM of 660,278,623,380 is 1085926380.
