Given numbers are 669,390,690,374,968

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

The LCM of 669,390,690,374,968 is 16458550680.

Find LCM of 669,390,690,374,968 with Prime Factorization

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

2 x 3 x 5 x 11 x 223 x 13 x 23 x 17 x 44 = 16458550680

Therefore, the lowest common multiple of 669,390,690,374,968 is 16458550680.

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 390 x 690 x 374 x 968 = 65175860692800

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

374 : 1, 2, 11, 17, 22, 34, 187, 374

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,390,690,374,968, is 1.

Now, the common factors can be found like this.

669:3x 223

390:2x 3x 5x 13

690:2x 3x 5x 23

374:2x 11x 17

968:2x 2x 2x 11x 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 2x 2x 3x 3x 5x 11 = 3960

Therefore, the value for common factors is 3960.

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 = 65175860692800/(1x3960)

LCM = 65175860692800/3960

LCM = 16458550680

Thus, we can understand that the LCM of 669,390,690,374,968 is 16458550680.
