Calculate the LCM of 654,746,399,312

Given numbers are 654,746,399,312

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

The LCM of 654,746,399,312 is 1687102872.

Find LCM of 654,746,399,312 with Prime Factorization


2 654, 746, 399, 312
3 327, 373, 399, 156
109, 373, 133, 52

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

2 x 3 x 109 x 373 x 133 x 52 = 1687102872

Therefore, the lowest common multiple of 654,746,399,312 is 1687102872.

LCM Formula to Find Lowest Common Multiple of 654,746,399,312

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.

654 x 746 x 399 x 312 = 60735703392

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

746 : 1, 2, 373, 746

399 : 1, 3, 7, 19, 21, 57, 133, 399

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,746,399,312, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

746:2x 373

399:3x 7x 19

312:2x 2x 2x 3x 13

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 60735703392/(1x36)

LCM = 60735703392/36

LCM = 1687102872

Thus, we can understand that the LCM of 654,746,399,312 is 1687102872.
