Given numbers are 397,660,848,856,403

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

The LCM of 397,660,848,856,403 is 2395295657040.

Find LCM of 397,660,848,856,403 with Prime Factorization

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

2 x 2 x 2 x 397 x 165 x 106 x 107 x 403 = 2395295657040

Therefore, the lowest common multiple of 397,660,848,856,403 is 2395295657040.

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.

397 x 660 x 848 x 856 x 403 = 76649461025280

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.

397 : 1, 397

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

856 : 1, 2, 4, 8, 107, 214, 428, 856

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,660,848,856,403, is 1.

Now, the common factors can be found like this.

397:397

660:2x 2x 3x 5x 11

848:2x 2x 2x 2x 53

856:2x 2x 2x 107

403:13x 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 2x 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 76649461025280/(1x32)

LCM = 76649461025280/32

LCM = 2395295657040

Thus, we can understand that the LCM of 397,660,848,856,403 is 2395295657040.
