The LCM of 798,284,912,785 is 355812240.

Find LCM of 798,284,912,785 with Prime Factorization


2 798, 284, 912, 785
2 399, 142, 456, 785
3 399, 71, 228, 785
19 133, 71, 76, 785
7, 71, 4, 785

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

2 x 2 x 3 x 19 x 7 x 71 x 4 x 785 = 355812240

Therefore, the lowest common multiple of 798,284,912,785 is 355812240.

LCM Formula to Find Lowest Common Multiple of 798,284,912,785

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.

798 x 284 x 912 x 785 = 162250381440

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

284 : 1, 2, 4, 71, 142, 284

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,284,912,785, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

284:2x 2x 71

912:2x 2x 2x 2x 3x 19

785:5x 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 3x 19 = 456

Therefore, the value for common factors is 456.

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 = 162250381440/(1x456)

LCM = 162250381440/456

LCM = 355812240

Thus, we can understand that the LCM of 798,284,912,785 is 355812240.
