Given numbers are 545,393,889,981

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

The LCM of 545,393,889,981 is 571231395.

Find LCM of 545,393,889,981 with Prime Factorization

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

3 x 109 x 5 x 131 x 889 x 3 = 571231395

Therefore, the lowest common multiple of 545,393,889,981 is 571231395.

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.

545 x 393 x 889 x 981 = 186792666165

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.

545 : 1, 5, 109, 545

393 : 1, 3, 131, 393

889 : 1, 7, 127, 889

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,393,889,981, is 1.

Now, the common factors can be found like this.

545:5x 109

393:3x 131

889:7x 127

981:3x 3x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 186792666165/(1x327)

LCM = 186792666165/327

LCM = 571231395

Thus, we can understand that the LCM of 545,393,889,981 is 571231395.
