Given numbers are 640,486,590,602,394

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

The LCM of 640,486,590,602,394 is 544090296960.

Find LCM of 640,486,590,602,394 with Prime Factorization

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

2 x 5 x 64 x 243 x 59 x 301 x 197 = 544090296960

Therefore, the lowest common multiple of 640,486,590,602,394 is 544090296960.

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 486 x 590 x 602 x 394 = 43527223756800

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

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

590 : 1, 2, 5, 10, 59, 118, 295, 590

602 : 1, 2, 7, 14, 43, 86, 301, 602

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,486,590,602,394, is 2.

Now, the common factors can be found like this.

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

486:2x 3x 3x 3x 3x 3

590:2x 5x 59

602:2x 7x 43

394:2x 197

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 5 = 40

Therefore, the value for common factors is 40.

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 = 43527223756800/(2x40)

LCM = 43527223756800/80

LCM = 544090296960

Thus, we can understand that the LCM of 640,486,590,602,394 is 544090296960.
