Given numbers are 640,283,778,349

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

The LCM of 640,283,778,349 is 24589032320.

Find LCM of 640,283,778,349 with Prime Factorization

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

2 x 320 x 283 x 389 x 349 = 24589032320

Therefore, the lowest common multiple of 640,283,778,349 is 24589032320.

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.

640 x 283 x 778 x 349 = 49178064640

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

283 : 1, 283

778 : 1, 2, 389, 778

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,283,778,349, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

283:283

778:2x 389

349:349

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

2 = 2

Therefore, the value for common factors is 2.

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 = 49178064640/(1x2)

LCM = 49178064640/2

LCM = 24589032320

Thus, we can understand that the LCM of 640,283,778,349 is 24589032320.
