Given numbers are 668,224,451,249

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

The LCM of 668,224,451,249 is 4200880992.

Find LCM of 668,224,451,249 with Prime Factorization

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

2 x 2 x 167 x 56 x 451 x 249 = 4200880992

Therefore, the lowest common multiple of 668,224,451,249 is 4200880992.

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 224 x 451 x 249 = 16803523968

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

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

451 : 1, 11, 41, 451

249 : 1, 3, 83, 249

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,224,451,249, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

224:2x 2x 2x 2x 2x 7

451:11x 41

249:3x 83

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 = 16803523968/(1x4)

LCM = 16803523968/4

LCM = 4200880992

Thus, we can understand that the LCM of 668,224,451,249 is 4200880992.
