The LCM of 421,258,684,621 is 854389188.

Find LCM of 421,258,684,621 with Prime Factorization


2 421, 258, 684, 621
3 421, 129, 342, 621
3 421, 43, 114, 207
421, 43, 38, 69

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

2 x 3 x 3 x 421 x 43 x 38 x 69 = 854389188

Therefore, the lowest common multiple of 421,258,684,621 is 854389188.

LCM Formula to Find Lowest Common Multiple of 421,258,684,621

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.

421 x 258 x 684 x 621 = 46137016152

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.

421 : 1, 421

258 : 1, 2, 3, 6, 43, 86, 129, 258

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,258,684,621, is 1.

Now, the common factors can be found like this.

421:421

258:2x 3x 43

684:2x 2x 3x 3x 19

621:3x 3x 3x 23

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 3 = 54

Therefore, the value for common factors is 54.

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 = 46137016152/(1x54)

LCM = 46137016152/54

LCM = 854389188

Thus, we can understand that the LCM of 421,258,684,621 is 854389188.
