Find LCM of 558,312,320,905 with Prime Factorization


2 558, 312, 320, 905
2 279, 156, 160, 905
2 279, 78, 80, 905
3 279, 39, 40, 905
5 93, 13, 40, 905
93, 13, 8, 181

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

2 x 2 x 2 x 3 x 5 x 93 x 13 x 8 x 181 = 210075840

Therefore, the lowest common multiple of 558,312,320,905 is 210075840.

LCM Formula to Find Lowest Common Multiple of 558,312,320,905

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.

558 x 312 x 320 x 905 = 50418201600

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.

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,312,320,905, is 1.

Now, the common factors can be found like this.

558:2x 3x 3x 31

312:2x 2x 2x 3x 13

320:2x 2x 2x 2x 2x 2x 5

905:5x 181

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 3x 5 = 240

Therefore, the value for common factors is 240.

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 = 50418201600/(1x240)

LCM = 50418201600/240

LCM = 210075840

Thus, we can understand that the LCM of 558,312,320,905 is 210075840.
