Given numbers are 547,974,392,655

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

The LCM of 547,974,392,655 is 68398039640.

Find LCM of 547,974,392,655 with Prime Factorization

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

2 x 547 x 487 x 196 x 655 = 68398039640

Therefore, the lowest common multiple of 547,974,392,655 is 68398039640.

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.

547 x 974 x 392 x 655 = 136796079280

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.

547 : 1, 547

974 : 1, 2, 487, 974

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,974,392,655, is 1.

Now, the common factors can be found like this.

547:547

974:2x 487

392:2x 2x 2x 7x 7

655:5x 131

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 = 136796079280/(1x2)

LCM = 136796079280/2

LCM = 68398039640

Thus, we can understand that the LCM of 547,974,392,655 is 68398039640.
