Given numbers are 649,903,396,596,420

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

The LCM of 649,903,396,596,420 is 5239260180.

Find LCM of 649,903,396,596,420 with Prime Factorization

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

2 x 2 x 3 x 7 x 11 x 59 x 43 x 3 x 149 x 5 = 5239260180

Therefore, the lowest common multiple of 649,903,396,596,420 is 5239260180.

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.

649 x 903 x 396 x 596 x 420 = 58092916875840

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.

649 : 1, 11, 59, 649

903 : 1, 3, 7, 21, 43, 129, 301, 903

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

596 : 1, 2, 4, 149, 298, 596

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,903,396,596,420, is 1.

Now, the common factors can be found like this.

649:11x 59

903:3x 7x 43

396:2x 2x 3x 3x 11

596:2x 2x 149

420:2x 2x 3x 5x 7

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 3x 3x 7x 11 = 11088

Therefore, the value for common factors is 11088.

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 = 58092916875840/(1x11088)

LCM = 58092916875840/11088

LCM = 5239260180

Thus, we can understand that the LCM of 649,903,396,596,420 is 5239260180.
