Given numbers are 388,640,115,517,122

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

The LCM of 388,640,115,517,122 is 45029790080.

Find LCM of 388,640,115,517,122 with Prime Factorization

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

2 x 2 x 5 x 97 x 32 x 23 x 517 x 61 = 45029790080

Therefore, the lowest common multiple of 388,640,115,517,122 is 45029790080.

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.

388 x 640 x 115 x 517 x 122 = 1801191603200

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.

388 : 1, 2, 4, 97, 194, 388

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

115 : 1, 5, 23, 115

517 : 1, 11, 47, 517

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,640,115,517,122, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

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

115:5x 23

517:11x 47

122:2x 61

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 = 1801191603200/(1x40)

LCM = 1801191603200/40

LCM = 45029790080

Thus, we can understand that the LCM of 388,640,115,517,122 is 45029790080.
