Given numbers are 407,782,247,140

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

The LCM of 407,782,247,140 is 5502957460.

Find LCM of 407,782,247,140 with Prime Factorization

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

2 x 407 x 391 x 247 x 70 = 5502957460

Therefore, the lowest common multiple of 407,782,247,140 is 5502957460.

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.

407 x 782 x 247 x 140 = 11005914920

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.

407 : 1, 11, 37, 407

782 : 1, 2, 17, 23, 34, 46, 391, 782

247 : 1, 13, 19, 247

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,782,247,140, is 1.

Now, the common factors can be found like this.

407:11x 37

782:2x 17x 23

247:13x 19

140:2x 2x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 11005914920/(1x2)

LCM = 11005914920/2

LCM = 5502957460

Thus, we can understand that the LCM of 407,782,247,140 is 5502957460.
