Given numbers are 658,674,142,888,990

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

The LCM of 658,674,142,888,990 is 1153402949160.

Find LCM of 658,674,142,888,990 with Prime Factorization

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

2 x 3 x 329 x 337 x 71 x 148 x 165 = 1153402949160

Therefore, the lowest common multiple of 658,674,142,888,990 is 1153402949160.

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.

658 x 674 x 142 x 888 x 990 = 55363341559680

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

674 : 1, 2, 337, 674

142 : 1, 2, 71, 142

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,674,142,888,990, is 2.

Now, the common factors can be found like this.

658:2x 7x 47

674:2x 337

142:2x 71

888:2x 2x 2x 3x 37

990:2x 3x 3x 5x 11

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 3 = 24

Therefore, the value for common factors is 24.

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 = 55363341559680/(2x24)

LCM = 55363341559680/48

LCM = 1153402949160

Thus, we can understand that the LCM of 658,674,142,888,990 is 1153402949160.
