Given numbers are 406,628,777,545,217

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

The LCM of 406,628,777,545,217 is 239076481980.

Find LCM of 406,628,777,545,217 with Prime Factorization

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

2 x 7 x 29 x 314 x 111 x 545 x 31 = 239076481980

Therefore, the lowest common multiple of 406,628,777,545,217 is 239076481980.

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.

406 x 628 x 777 x 545 x 217 = 23429495234040

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

628 : 1, 2, 4, 157, 314, 628

777 : 1, 3, 7, 21, 37, 111, 259, 777

545 : 1, 5, 109, 545

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,628,777,545,217, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

628:2x 2x 157

777:3x 7x 37

545:5x 109

217:7x 31

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 23429495234040/(1x98)

LCM = 23429495234040/98

LCM = 239076481980

Thus, we can understand that the LCM of 406,628,777,545,217 is 239076481980.
