Given numbers are 574,186,660,978,381

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

The LCM of 574,186,660,978,381 is 121556686020.

Find LCM of 574,186,660,978,381 with Prime Factorization

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

2 x 3 x 287 x 31 x 110 x 163 x 127 = 121556686020

Therefore, the lowest common multiple of 574,186,660,978,381 is 121556686020.

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.

574 x 186 x 660 x 978 x 381 = 26256244180320

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.

574 : 1, 2, 7, 14, 41, 82, 287, 574

186 : 1, 2, 3, 6, 31, 62, 93, 186

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

978 : 1, 2, 3, 6, 163, 326, 489, 978

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,186,660,978,381, is 1.

Now, the common factors can be found like this.

574:2x 7x 41

186:2x 3x 31

660:2x 2x 3x 5x 11

978:2x 3x 163

381:3x 127

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 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 26256244180320/(1x216)

LCM = 26256244180320/216

LCM = 121556686020

Thus, we can understand that the LCM of 574,186,660,978,381 is 121556686020.
