The LCM of 995,918,646,625 is 2169348750.

Find LCM of 995,918,646,625 with Prime Factorization


2 995, 918, 646, 625
5 995, 459, 323, 625
17 199, 459, 323, 125
199, 27, 19, 125

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

2 x 5 x 17 x 199 x 27 x 19 x 125 = 2169348750

Therefore, the lowest common multiple of 995,918,646,625 is 2169348750.

LCM Formula to Find Lowest Common Multiple of 995,918,646,625

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.

995 x 918 x 646 x 625 = 368789287500

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.

995 : 1, 5, 199, 995

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

646 : 1, 2, 17, 19, 34, 38, 323, 646

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,918,646,625, is 1.

Now, the common factors can be found like this.

995:5x 199

918:2x 3x 3x 3x 17

646:2x 17x 19

625:5x 5x 5x 5

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

2x 5x 17 = 170

Therefore, the value for common factors is 170.

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 = 368789287500/(1x170)

LCM = 368789287500/170

LCM = 2169348750

Thus, we can understand that the LCM of 995,918,646,625 is 2169348750.
