Given numbers are 669,406,578,464

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

The LCM of 669,406,578,464 is 627971568.

Find LCM of 669,406,578,464 with Prime Factorization

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

2 x 29 x 669 x 7 x 289 x 8 = 627971568

Therefore, the lowest common multiple of 669,406,578,464 is 627971568.

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.

669 x 406 x 578 x 464 = 72844701888

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.

669 : 1, 3, 223, 669

406 : 1, 2, 7, 14, 29, 58, 203, 406

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

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,406,578,464, is 1.

Now, the common factors can be found like this.

669:3x 223

406:2x 7x 29

578:2x 17x 17

464:2x 2x 2x 2x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 72844701888/(1x116)

LCM = 72844701888/116

LCM = 627971568

Thus, we can understand that the LCM of 669,406,578,464 is 627971568.
