Given numbers are 605,637,221,553

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

The LCM of 605,637,221,553 is 517572055.

Find LCM of 605,637,221,553 with Prime Factorization

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

7 x 13 x 605 x 7 x 17 x 79 = 517572055

Therefore, the lowest common multiple of 605,637,221,553 is 517572055.

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.

605 x 637 x 221 x 553 = 47099057005

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.

605 : 1, 5, 11, 55, 121, 605

637 : 1, 7, 13, 49, 91, 637

221 : 1, 13, 17, 221

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,637,221,553, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

637:7x 7x 13

221:13x 17

553:7x 79

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 47099057005/(1x91)

LCM = 47099057005/91

LCM = 517572055

Thus, we can understand that the LCM of 605,637,221,553 is 517572055.
