Given numbers are 515,737,420,128

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

The LCM of 515,737,420,128 is 1020243840.

Find LCM of 515,737,420,128 with Prime Factorization

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

2 x 2 x 5 x 103 x 737 x 21 x 32 = 1020243840

Therefore, the lowest common multiple of 515,737,420,128 is 1020243840.

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.

515 x 737 x 420 x 128 = 20404876800

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.

515 : 1, 5, 103, 515

737 : 1, 11, 67, 737

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,737,420,128, is 1.

Now, the common factors can be found like this.

515:5x 103

737:11x 67

420:2x 2x 3x 5x 7

128:2x 2x 2x 2x 2x 2x 2

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 5 = 20

Therefore, the value for common factors is 20.

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 = 20404876800/(1x20)

LCM = 20404876800/20

LCM = 1020243840

Thus, we can understand that the LCM of 515,737,420,128 is 1020243840.
