Given numbers are 438,702,624,320,251

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

The LCM of 438,702,624,320,251 is 2058039360.

Find LCM of 438,702,624,320,251 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 13 x 73 x 9 x 1 x 20 x 251 = 2058039360

Therefore, the lowest common multiple of 438,702,624,320,251 is 2058039360.

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.

438 x 702 x 624 x 320 x 251 = 15410598727680

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,702,624,320,251, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

702:2x 3x 3x 3x 13

624:2x 2x 2x 2x 3x 13

320:2x 2x 2x 2x 2x 2x 5

251:251

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 2x 2x 2x 3x 3x 13 = 7488

Therefore, the value for common factors is 7488.

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 = 15410598727680/(1x7488)

LCM = 15410598727680/7488

LCM = 2058039360

Thus, we can understand that the LCM of 438,702,624,320,251 is 2058039360.
