Given numbers are 418,192,931,578,686

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

The LCM of 418,192,931,578,686 is 3977768256.

Find LCM of 418,192,931,578,686 with Prime Factorization

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

2 x 7 x 7 x 19 x 11 x 96 x 1 x 289 x 7 = 3977768256

Therefore, the lowest common multiple of 418,192,931,578,686 is 3977768256.

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.

418 x 192 x 931 x 578 x 686 = 29626417970688

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

931 : 1, 7, 19, 49, 133, 931

578 : 1, 2, 17, 34, 289, 578

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,192,931,578,686, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

192:2x 2x 2x 2x 2x 2x 3

931:7x 7x 19

578:2x 17x 17

686:2x 7x 7x 7

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 2x 7x 7x 19 = 7448

Therefore, the value for common factors is 7448.

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 = 29626417970688/(1x7448)

LCM = 29626417970688/7448

LCM = 3977768256

Thus, we can understand that the LCM of 418,192,931,578,686 is 3977768256.
