Given numbers are 122,578,983,440

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

The LCM of 122,578,983,440 is 7624895080.

Find LCM of 122,578,983,440 with Prime Factorization

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

2 x 61 x 289 x 983 x 220 = 7624895080

Therefore, the lowest common multiple of 122,578,983,440 is 7624895080.

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.

122 x 578 x 983 x 440 = 30499580320

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.

122 : 1, 2, 61, 122

578 : 1, 2, 17, 34, 289, 578

983 : 1, 983

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,578,983,440, is 1.

Now, the common factors can be found like this.

122:2x 61

578:2x 17x 17

983:983

440:2x 2x 2x 5x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30499580320/(1x4)

LCM = 30499580320/4

LCM = 7624895080

Thus, we can understand that the LCM of 122,578,983,440 is 7624895080.
