Given numbers are 670,880,730,838,660

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

The LCM of 670,880,730,838,660 is 5410228560.

Find LCM of 670,880,730,838,660 with Prime Factorization

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

2 x 2 x 5 x 11 x 67 x 4 x 73 x 419 x 3 = 5410228560

Therefore, the lowest common multiple of 670,880,730,838,660 is 5410228560.

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 880 x 730 x 838 x 660 = 238050056640000

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

730 : 1, 2, 5, 10, 73, 146, 365, 730

838 : 1, 2, 419, 838

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,880,730,838,660, is 2.

Now, the common factors can be found like this.

670:2x 5x 67

880:2x 2x 2x 2x 5x 11

730:2x 5x 73

838:2x 419

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 2x 5x 5x 5x 11 = 22000

Therefore, the value for common factors is 22000.

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 = 238050056640000/(2x22000)

LCM = 238050056640000/44000

LCM = 5410228560

Thus, we can understand that the LCM of 670,880,730,838,660 is 5410228560.
