Given numbers are 642,853,994,838

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

The LCM of 642,853,994,838 is 114039281118.

Find LCM of 642,853,994,838 with Prime Factorization

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

2 x 321 x 853 x 497 x 419 = 114039281118

Therefore, the lowest common multiple of 642,853,994,838 is 114039281118.

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.

642 x 853 x 994 x 838 = 456157124472

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

853 : 1, 853

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

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,853,994,838, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

853:853

994:2x 7x 71

838:2x 419

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 = 456157124472/(1x4)

LCM = 456157124472/4

LCM = 114039281118

Thus, we can understand that the LCM of 642,853,994,838 is 114039281118.
