Calculate the LCM of 684,731,609,402

Given numbers are 684,731,609,402

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 684,731,609,402 is 6800554404.

Find LCM of 684,731,609,402 with Prime Factorization


2 684, 731, 609, 402
3 342, 731, 609, 201
114, 731, 203, 67

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

2 x 3 x 114 x 731 x 203 x 67 = 6800554404

Therefore, the lowest common multiple of 684,731,609,402 is 6800554404.

LCM Formula to Find Lowest Common Multiple of 684,731,609,402

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.

684 x 731 x 609 x 402 = 122409979272

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.

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

731 : 1, 17, 43, 731

609 : 1, 3, 7, 21, 29, 87, 203, 609

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,731,609,402, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

731:17x 43

609:3x 7x 29

402:2x 3x 67

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 3 = 18

Therefore, the value for common factors is 18.

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 = 122409979272/(1x18)

LCM = 122409979272/18

LCM = 6800554404

Thus, we can understand that the LCM of 684,731,609,402 is 6800554404.
