Calculate the LCM of 619,646,320,494

Given numbers are 619,646,320,494

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

The LCM of 619,646,320,494 is 831737920.

Find LCM of 619,646,320,494 with Prime Factorization


2 619, 646, 320, 494
19 619, 323, 160, 247
619, 17, 160, 13

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

2 x 19 x 619 x 17 x 160 x 13 = 831737920

Therefore, the lowest common multiple of 619,646,320,494 is 831737920.

LCM Formula to Find Lowest Common Multiple of 619,646,320,494

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.

619 x 646 x 320 x 494 = 63212081920

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.

619 : 1, 619

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

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

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 619,646,320,494, is 1.

Now, the common factors can be found like this.

619:619

646:2x 17x 19

320:2x 2x 2x 2x 2x 2x 5

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 19 = 76

Therefore, the value for common factors is 76.

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 = 63212081920/(1x76)

LCM = 63212081920/76

LCM = 831737920

Thus, we can understand that the LCM of 619,646,320,494 is 831737920.
