Given numbers are 540,770,418,418

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

The LCM of 540,770,418,418 is 790020.

Find LCM of 540,770,418,418 with Prime Factorization

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

2 x 5 x 11 x 19 x 54 x 7 x 1 x 1 = 790020

Therefore, the lowest common multiple of 540,770,418,418 is 790020.

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 770 x 418 x 418 = 72650239200

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

418 : 1, 2, 11, 19, 22, 38, 209, 418

418 : 1, 2, 11, 19, 22, 38, 209, 418

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,770,418,418, is 2.

Now, the common factors can be found like this.

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

770:2x 5x 7x 11

418:2x 11x 19

418:2x 11x 19

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 5x 11x 11x 19 = 45980

Therefore, the value for common factors is 45980.

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 = 72650239200/(2x45980)

LCM = 72650239200/91960

LCM = 790020

Thus, we can understand that the LCM of 540,770,418,418 is 790020.
