Given numbers are 660,728,770,157

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

The LCM of 660,728,770,157 is 18858840.

Find LCM of 660,728,770,157 with Prime Factorization

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

2 x 2 x 5 x 7 x 11 x 3 x 26 x 1 x 157 = 18858840

Therefore, the lowest common multiple of 660,728,770,157 is 18858840.

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.

660 x 728 x 770 x 157 = 58085227200

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.

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

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

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

157 : 1, 157

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,728,770,157, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

728:2x 2x 2x 7x 13

770:2x 5x 7x 11

157:157

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 7x 11 = 3080

Therefore, the value for common factors is 3080.

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 = 58085227200/(1x3080)

LCM = 58085227200/3080

LCM = 18858840

Thus, we can understand that the LCM of 660,728,770,157 is 18858840.
