Given numbers are 540,862,160,391

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

The LCM of 540,862,160,391 is 728010720.

Find LCM of 540,862,160,391 with Prime Factorization

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

2 x 2 x 5 x 27 x 431 x 8 x 391 = 728010720

Therefore, the lowest common multiple of 540,862,160,391 is 728010720.

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.

540 x 862 x 160 x 391 = 29120428800

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.

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

862 : 1, 2, 431, 862

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,862,160,391, is 1.

Now, the common factors can be found like this.

540:2x 2x 3x 3x 3x 5

862:2x 431

160:2x 2x 2x 2x 2x 5

391:17x 23

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 5 = 40

Therefore, the value for common factors is 40.

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 = 29120428800/(1x40)

LCM = 29120428800/40

LCM = 728010720

Thus, we can understand that the LCM of 540,862,160,391 is 728010720.
