Given numbers are 782,478,873,455

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

The LCM of 782,478,873,455 is 74238689070.

Find LCM of 782,478,873,455 with Prime Factorization

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

2 x 391 x 239 x 873 x 455 = 74238689070

Therefore, the lowest common multiple of 782,478,873,455 is 74238689070.

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.

782 x 478 x 873 x 455 = 148477378140

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.

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

478 : 1, 2, 239, 478

873 : 1, 3, 9, 97, 291, 873

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,478,873,455, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

478:2x 239

873:3x 3x 97

455:5x 7x 13

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 = 148477378140/(1x2)

LCM = 148477378140/2

LCM = 74238689070

Thus, we can understand that the LCM of 782,478,873,455 is 74238689070.
