Given numbers are 303,778,140,721

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

The LCM of 303,778,140,721 is 1699642140.

Find LCM of 303,778,140,721 with Prime Factorization

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

2 x 7 x 303 x 389 x 10 x 103 = 1699642140

Therefore, the lowest common multiple of 303,778,140,721 is 1699642140.

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.

303 x 778 x 140 x 721 = 23794989960

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.

303 : 1, 3, 101, 303

778 : 1, 2, 389, 778

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,778,140,721, is 1.

Now, the common factors can be found like this.

303:3x 101

778:2x 389

140:2x 2x 5x 7

721:7x 103

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 23794989960/(1x14)

LCM = 23794989960/14

LCM = 1699642140

Thus, we can understand that the LCM of 303,778,140,721 is 1699642140.
