Given numbers are 670,436,290,728,902

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

The LCM of 670,436,290,728,902 is 347678010680.

Find LCM of 670,436,290,728,902 with Prime Factorization

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

2 x 2 x 5 x 67 x 109 x 29 x 182 x 451 = 347678010680

Therefore, the lowest common multiple of 670,436,290,728,902 is 347678010680.

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 436 x 290 x 728 x 902 = 55628481708800

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

436 : 1, 2, 4, 109, 218, 436

290 : 1, 2, 5, 10, 29, 58, 145, 290

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

902 : 1, 2, 11, 22, 41, 82, 451, 902

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,436,290,728,902, is 2.

Now, the common factors can be found like this.

670:2x 5x 67

436:2x 2x 109

290:2x 5x 29

728:2x 2x 2x 7x 13

902:2x 11x 41

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 5 = 80

Therefore, the value for common factors is 80.

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 = 55628481708800/(2x80)

LCM = 55628481708800/160

LCM = 347678010680

Thus, we can understand that the LCM of 670,436,290,728,902 is 347678010680.
