Given numbers are 578,661,958,646

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

The LCM of 578,661,958,646 is 3477109858.

Find LCM of 578,661,958,646 with Prime Factorization

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

2 x 17 x 17 x 661 x 479 x 19 = 3477109858

Therefore, the lowest common multiple of 578,661,958,646 is 3477109858.

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.

578 x 661 x 958 x 646 = 236443470344

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.

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

661 : 1, 661

958 : 1, 2, 479, 958

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,661,958,646, is 1.

Now, the common factors can be found like this.

578:2x 17x 17

661:661

958:2x 479

646:2x 17x 19

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 17 = 68

Therefore, the value for common factors is 68.

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 = 236443470344/(1x68)

LCM = 236443470344/68

LCM = 3477109858

Thus, we can understand that the LCM of 578,661,958,646 is 3477109858.
