Given numbers are 658,685,730,121

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

The LCM of 658,685,730,121 is 3981298090.

Find LCM of 658,685,730,121 with Prime Factorization

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

2 x 5 x 329 x 137 x 73 x 121 = 3981298090

Therefore, the lowest common multiple of 658,685,730,121 is 3981298090.

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.

658 x 685 x 730 x 121 = 39812980900

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

685 : 1, 5, 137, 685

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

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,685,730,121, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

685:5x 137

730:2x 5x 73

121:11x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 39812980900/(1x10)

LCM = 39812980900/10

LCM = 3981298090

Thus, we can understand that the LCM of 658,685,730,121 is 3981298090.
