Given numbers are 720,937,390,685

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

The LCM of 720,937,390,685 is 1201533840.

Find LCM of 720,937,390,685 with Prime Factorization

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

2 x 3 x 5 x 24 x 937 x 13 x 137 = 1201533840

Therefore, the lowest common multiple of 720,937,390,685 is 1201533840.

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 937 x 390 x 685 = 180230076000

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

937 : 1, 937

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,937,390,685, is 1.

Now, the common factors can be found like this.

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

937:937

390:2x 3x 5x 13

685:5x 137

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

2x 3x 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 180230076000/(1x150)

LCM = 180230076000/150

LCM = 1201533840

Thus, we can understand that the LCM of 720,937,390,685 is 1201533840.
