Find LCM of 688,925,320,310 with Prime Factorization


2 688, 925, 320, 310
2 344, 925, 160, 155
2 172, 925, 80, 155
2 86, 925, 40, 155
5 43, 925, 20, 155
43, 185, 4, 31

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

2 x 2 x 2 x 2 x 5 x 43 x 185 x 4 x 31 = 78913600

Therefore, the lowest common multiple of 688,925,320,310 is 78913600.

LCM Formula to Find Lowest Common Multiple of 688,925,320,310

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.

688 x 925 x 320 x 310 = 63130880000

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

925 : 1, 5, 25, 37, 185, 925

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

310 : 1, 2, 5, 10, 31, 62, 155, 310

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,925,320,310, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

925:5x 5x 37

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

310:2x 5x 31

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 2x 5x 5 = 800

Therefore, the value for common factors is 800.

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 = 63130880000/(1x800)

LCM = 63130880000/800

LCM = 78913600

Thus, we can understand that the LCM of 688,925,320,310 is 78913600.
