Given numbers are 649,697,720,915,422

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

The LCM of 649,697,720,915,422 is 4192009533360.

Find LCM of 649,697,720,915,422 with Prime Factorization

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

2 x 3 x 5 x 649 x 697 x 24 x 61 x 211 = 4192009533360

Therefore, the lowest common multiple of 649,697,720,915,422 is 4192009533360.

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 697 x 720 x 915 x 422 = 125760286000800

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

697 : 1, 17, 41, 697

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

915 : 1, 3, 5, 15, 61, 183, 305, 915

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,697,720,915,422, is 1.

Now, the common factors can be found like this.

649:11x 59

697:17x 41

720:2x 2x 2x 2x 3x 3x 5

915:3x 5x 61

422:2x 211

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 125760286000800/(1x30)

LCM = 125760286000800/30

LCM = 4192009533360

Thus, we can understand that the LCM of 649,697,720,915,422 is 4192009533360.
