Given numbers are 670,455,145,416,660

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

The LCM of 670,455,145,416,660 is 933572640.

Find LCM of 670,455,145,416,660 with Prime Factorization

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

2 x 2 x 5 x 13 x 67 x 7 x 29 x 8 x 33 = 933572640

Therefore, the lowest common multiple of 670,455,145,416,660 is 933572640.

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.

670 x 455 x 145 x 416 x 660 = 12136444320000

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

455 : 1, 5, 7, 13, 35, 65, 91, 455

145 : 1, 5, 29, 145

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,455,145,416,660, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

455:5x 7x 13

145:5x 29

416:2x 2x 2x 2x 2x 13

660:2x 2x 3x 5x 11

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 5x 5x 5x 13 = 13000

Therefore, the value for common factors is 13000.

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 = 12136444320000/(1x13000)

LCM = 12136444320000/13000

LCM = 933572640

Thus, we can understand that the LCM of 670,455,145,416,660 is 933572640.
