Given numbers are 628,646,515,648,736

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

The LCM of 628,646,515,648,736 is 1556941292640.

Find LCM of 628,646,515,648,736 with Prime Factorization

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

2 x 2 x 2 x 157 x 323 x 515 x 81 x 92 = 1556941292640

Therefore, the lowest common multiple of 628,646,515,648,736 is 1556941292640.

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.

628 x 646 x 515 x 648 x 736 = 99644242728960

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.

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

515 : 1, 5, 103, 515

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,646,515,648,736, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

646:2x 17x 19

515:5x 103

648:2x 2x 2x 3x 3x 3x 3

736:2x 2x 2x 2x 2x 23

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 99644242728960/(1x64)

LCM = 99644242728960/64

LCM = 1556941292640

Thus, we can understand that the LCM of 628,646,515,648,736 is 1556941292640.
