Given numbers are 668,121,752,821

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

The LCM of 668,121,752,821 is 12475640144.

Find LCM of 668,121,752,821 with Prime Factorization

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

2 x 2 x 167 x 121 x 188 x 821 = 12475640144

Therefore, the lowest common multiple of 668,121,752,821 is 12475640144.

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.

668 x 121 x 752 x 821 = 49902560576

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.

668 : 1, 2, 4, 167, 334, 668

121 : 1, 11, 121

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,121,752,821, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

121:11x 11

752:2x 2x 2x 2x 47

821:821

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 = 49902560576/(1x4)

LCM = 49902560576/4

LCM = 12475640144

Thus, we can understand that the LCM of 668,121,752,821 is 12475640144.
