Given numbers are 907,322,540,721

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

The LCM of 907,322,540,721 is 8122021740.

Find LCM of 907,322,540,721 with Prime Factorization

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

2 x 7 x 907 x 23 x 270 x 103 = 8122021740

Therefore, the lowest common multiple of 907,322,540,721 is 8122021740.

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.

907 x 322 x 540 x 721 = 113708304360

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.

907 : 1, 907

322 : 1, 2, 7, 14, 23, 46, 161, 322

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,322,540,721, is 1.

Now, the common factors can be found like this.

907:907

322:2x 7x 23

540:2x 2x 3x 3x 3x 5

721:7x 103

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 113708304360/(1x14)

LCM = 113708304360/14

LCM = 8122021740

Thus, we can understand that the LCM of 907,322,540,721 is 8122021740.
