Given numbers are 487,974,782,740

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

The LCM of 487,974,782,740 is 140908580.

Find LCM of 487,974,782,740 with Prime Factorization

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

2 x 487 x 1 x 1 x 391 x 370 = 140908580

Therefore, the lowest common multiple of 487,974,782,740 is 140908580.

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.

487 x 974 x 782 x 740 = 274489913840

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.

487 : 1, 487

974 : 1, 2, 487, 974

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

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,974,782,740, is 1.

Now, the common factors can be found like this.

487:487

974:2x 487

782:2x 17x 23

740:2x 2x 5x 37

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 487 = 1948

Therefore, the value for common factors is 1948.

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 = 274489913840/(1x1948)

LCM = 274489913840/1948

LCM = 140908580

Thus, we can understand that the LCM of 487,974,782,740 is 140908580.
