The LCM of 327,620,902,442 is 20207298540.

Find LCM of 327,620,902,442 with Prime Factorization


2 327, 620, 902, 442
327, 310, 451, 221

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

2 x 327 x 310 x 451 x 221 = 20207298540

Therefore, the lowest common multiple of 327,620,902,442 is 20207298540.

LCM Formula to Find Lowest Common Multiple of 327,620,902,442

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.

327 x 620 x 902 x 442 = 80829194160

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.

327 : 1, 3, 109, 327

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,620,902,442, is 1.

Now, the common factors can be found like this.

327:3x 109

620:2x 2x 5x 31

902:2x 11x 41

442:2x 13x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 80829194160/(1x4)

LCM = 80829194160/4

LCM = 20207298540

Thus, we can understand that the LCM of 327,620,902,442 is 20207298540.
