Given numbers are 577,221,455,418

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

The LCM of 577,221,455,418 is 1865573710.

Find LCM of 577,221,455,418 with Prime Factorization

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

13 x 577 x 17 x 35 x 418 = 1865573710

Therefore, the lowest common multiple of 577,221,455,418 is 1865573710.

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.

577 x 221 x 455 x 418 = 24252458230

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.

577 : 1, 577

221 : 1, 13, 17, 221

455 : 1, 5, 7, 13, 35, 65, 91, 455

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,221,455,418, is 1.

Now, the common factors can be found like this.

577:577

221:13x 17

455:5x 7x 13

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 24252458230/(1x13)

LCM = 24252458230/13

LCM = 1865573710

Thus, we can understand that the LCM of 577,221,455,418 is 1865573710.
