Calculate the LCM of 690,325,718,494

Given numbers are 690,325,718,494

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

The LCM of 690,325,718,494 is 305921850.

Find LCM of 690,325,718,494 with Prime Factorization


2 690, 325, 718, 494
5 345, 325, 359, 247
13 69, 65, 359, 247
69, 5, 359, 19

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

2 x 5 x 13 x 69 x 5 x 359 x 19 = 305921850

Therefore, the lowest common multiple of 690,325,718,494 is 305921850.

LCM Formula to Find Lowest Common Multiple of 690,325,718,494

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.

690 x 325 x 718 x 494 = 79539681000

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

325 : 1, 5, 13, 25, 65, 325

718 : 1, 2, 359, 718

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,325,718,494, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

325:5x 5x 13

718:2x 359

494:2x 13x 19

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 5x 13 = 260

Therefore, the value for common factors is 260.

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 = 79539681000/(1x260)

LCM = 79539681000/260

LCM = 305921850

Thus, we can understand that the LCM of 690,325,718,494 is 305921850.
