Given numbers are 702,742,728,203

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

The LCM of 702,742,728,203 is 30211272.

Find LCM of 702,742,728,203 with Prime Factorization

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

2 x 7 x 13 x 27 x 53 x 4 x 29 = 30211272

Therefore, the lowest common multiple of 702,742,728,203 is 30211272.

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.

702 x 742 x 728 x 203 = 76978321056

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

742 : 1, 2, 7, 14, 53, 106, 371, 742

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,742,728,203, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

742:2x 7x 53

728:2x 2x 2x 7x 13

203:7x 29

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 7x 7x 13 = 2548

Therefore, the value for common factors is 2548.

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 = 76978321056/(1x2548)

LCM = 76978321056/2548

LCM = 30211272

Thus, we can understand that the LCM of 702,742,728,203 is 30211272.
