Given numbers are 857,542,978,994

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

The LCM of 857,542,978,994 is 112887370302.

Find LCM of 857,542,978,994 with Prime Factorization

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

2 x 857 x 271 x 489 x 497 = 112887370302

Therefore, the lowest common multiple of 857,542,978,994 is 112887370302.

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.

857 x 542 x 978 x 994 = 451549481208

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.

857 : 1, 857

542 : 1, 2, 271, 542

978 : 1, 2, 3, 6, 163, 326, 489, 978

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,542,978,994, is 1.

Now, the common factors can be found like this.

857:857

542:2x 271

978:2x 3x 163

994:2x 7x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 451549481208/(1x4)

LCM = 451549481208/4

LCM = 112887370302

Thus, we can understand that the LCM of 857,542,978,994 is 112887370302.
