Given numbers are 640,733,930,644,497

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

The LCM of 640,733,930,644,497 is 498713496960.

Find LCM of 640,733,930,644,497 with Prime Factorization

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

2 x 2 x 5 x 7 x 32 x 733 x 93 x 23 x 71 = 498713496960

Therefore, the lowest common multiple of 640,733,930,644,497 is 498713496960.

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 733 x 930 x 644 x 497 = 139639779148800

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

733 : 1, 733

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,733,930,644,497, is 1.

Now, the common factors can be found like this.

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

733:733

930:2x 3x 5x 31

644:2x 2x 7x 23

497:7x 71

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 5x 7 = 280

Therefore, the value for common factors is 280.

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 = 139639779148800/(1x280)

LCM = 139639779148800/280

LCM = 498713496960

Thus, we can understand that the LCM of 640,733,930,644,497 is 498713496960.
