Find LCM of 822,555,981,245,620 with Prime Factorization


2 822, 555, 981, 245, 620
3 411, 555, 981, 245, 310
5 137, 185, 327, 245, 310
137, 37, 327, 49, 62

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

2 x 3 x 5 x 137 x 37 x 327 x 49 x 62 = 151070291820

Therefore, the lowest common multiple of 822,555,981,245,620 is 151070291820.

LCM Formula to Find Lowest Common Multiple of 822,555,981,245,620

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.

822 x 555 x 981 x 245 x 620 = 67981631319000

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.

822 : 1, 2, 3, 6, 137, 274, 411, 822

555 : 1, 3, 5, 15, 37, 111, 185, 555

981 : 1, 3, 9, 109, 327, 981

245 : 1, 5, 7, 35, 49, 245

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,555,981,245,620, is 1.

Now, the common factors can be found like this.

822:2x 3x 137

555:3x 5x 37

981:3x 3x 109

245:5x 7x 7

620:2x 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 3x 3x 5x 5 = 450

Therefore, the value for common factors is 450.

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 = 67981631319000/(1x450)

LCM = 67981631319000/450

LCM = 151070291820

Thus, we can understand that the LCM of 822,555,981,245,620 is 151070291820.
