Given numbers are 126,720,628,366,394

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

The LCM of 126,720,628,366,394 is 9508811760.

Find LCM of 126,720,628,366,394 with Prime Factorization

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

2 x 2 x 3 x 3 x 7 x 20 x 157 x 61 x 197 = 9508811760

Therefore, the lowest common multiple of 126,720,628,366,394 is 9508811760.

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.

126 x 720 x 628 x 366 x 394 = 8215613360640

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

628 : 1, 2, 4, 157, 314, 628

366 : 1, 2, 3, 6, 61, 122, 183, 366

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,720,628,366,394, is 2.

Now, the common factors can be found like this.

126:2x 3x 3x 7

720:2x 2x 2x 2x 3x 3x 5

628:2x 2x 157

366:2x 3x 61

394:2x 197

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 2x 3x 3x 3 = 432

Therefore, the value for common factors is 432.

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 = 8215613360640/(2x432)

LCM = 8215613360640/864

LCM = 9508811760

Thus, we can understand that the LCM of 126,720,628,366,394 is 9508811760.
