Given numbers are 702,638,455,988

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

The LCM of 702,638,455,988 is 297837540.

Find LCM of 702,638,455,988 with Prime Factorization

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

2 x 13 x 27 x 319 x 35 x 38 = 297837540

Therefore, the lowest common multiple of 702,638,455,988 is 297837540.

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.

702 x 638 x 455 x 988 = 201338177040

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,638,455,988, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

638:2x 11x 29

455:5x 7x 13

988:2x 2x 13x 19

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 13x 13 = 676

Therefore, the value for common factors is 676.

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 = 201338177040/(1x676)

LCM = 201338177040/676

LCM = 297837540

Thus, we can understand that the LCM of 702,638,455,988 is 297837540.
