Given numbers are 840,734,478,169,555

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

The LCM of 840,734,478,169,555 is 460714286760.

Find LCM of 840,734,478,169,555 with Prime Factorization

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

2 x 3 x 5 x 28 x 367 x 239 x 169 x 37 = 460714286760

Therefore, the lowest common multiple of 840,734,478,169,555 is 460714286760.

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.

840 x 734 x 478 x 169 x 555 = 27642857205600

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

734 : 1, 2, 367, 734

478 : 1, 2, 239, 478

169 : 1, 13, 169

555 : 1, 3, 5, 15, 37, 111, 185, 555

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,734,478,169,555, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

734:2x 367

478:2x 239

169:13x 13

555:3x 5x 37

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 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 27642857205600/(1x60)

LCM = 27642857205600/60

LCM = 460714286760

Thus, we can understand that the LCM of 840,734,478,169,555 is 460714286760.
