Given numbers are 555,548,221,784

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

The LCM of 555,548,221,784 is 13174128240.

Find LCM of 555,548,221,784 with Prime Factorization

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

2 x 2 x 555 x 137 x 221 x 196 = 13174128240

Therefore, the lowest common multiple of 555,548,221,784 is 13174128240.

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.

555 x 548 x 221 x 784 = 52696512960

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.

555 : 1, 3, 5, 15, 37, 111, 185, 555

548 : 1, 2, 4, 137, 274, 548

221 : 1, 13, 17, 221

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,548,221,784, is 1.

Now, the common factors can be found like this.

555:3x 5x 37

548:2x 2x 137

221:13x 17

784:2x 2x 2x 2x 7x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 52696512960/(1x4)

LCM = 52696512960/4

LCM = 13174128240

Thus, we can understand that the LCM of 555,548,221,784 is 13174128240.
