Given numbers are 857,988,493,638

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

The LCM of 857,988,493,638 is 4591740868.

Find LCM of 857,988,493,638 with Prime Factorization

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

2 x 29 x 857 x 494 x 17 x 11 = 4591740868

Therefore, the lowest common multiple of 857,988,493,638 is 4591740868.

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 988 x 493 x 638 = 266320970344

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

493 : 1, 17, 29, 493

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,988,493,638, is 1.

Now, the common factors can be found like this.

857:857

988:2x 2x 13x 19

493:17x 29

638:2x 11x 29

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

2x 29 = 58

Therefore, the value for common factors is 58.

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 = 266320970344/(1x58)

LCM = 266320970344/58

LCM = 4591740868

Thus, we can understand that the LCM of 857,988,493,638 is 4591740868.
