Given numbers are 640,936,673,248,437

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

The LCM of 640,936,673,248,437 is 682690769280.

Find LCM of 640,936,673,248,437 with Prime Factorization

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

2 x 2 x 2 x 80 x 117 x 673 x 31 x 437 = 682690769280

Therefore, the lowest common multiple of 640,936,673,248,437 is 682690769280.

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 936 x 673 x 248 x 437 = 43692209233920

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

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

673 : 1, 673

248 : 1, 2, 4, 8, 31, 62, 124, 248

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,936,673,248,437, is 1.

Now, the common factors can be found like this.

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

936:2x 2x 2x 3x 3x 13

673:673

248:2x 2x 2x 31

437:19x 23

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 43692209233920/(1x64)

LCM = 43692209233920/64

LCM = 682690769280

Thus, we can understand that the LCM of 640,936,673,248,437 is 682690769280.
