Given numbers are 720,484,428,281,757

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

The LCM of 720,484,428,281,757 is 1982913839280.

Find LCM of 720,484,428,281,757 with Prime Factorization

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

2 x 2 x 180 x 121 x 107 x 281 x 757 = 1982913839280

Therefore, the lowest common multiple of 720,484,428,281,757 is 1982913839280.

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.

720 x 484 x 428 x 281 x 757 = 31726621428480

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.

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

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

428 : 1, 2, 4, 107, 214, 428

281 : 1, 281

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,484,428,281,757, is 1.

Now, the common factors can be found like this.

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

484:2x 2x 11x 11

428:2x 2x 107

281:281

757:757

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 2 = 16

Therefore, the value for common factors is 16.

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 = 31726621428480/(1x16)

LCM = 31726621428480/16

LCM = 1982913839280

Thus, we can understand that the LCM of 720,484,428,281,757 is 1982913839280.
