Given numbers are 278,350,649,356

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

The LCM of 278,350,649,356 is 5620145300.

Find LCM of 278,350,649,356 with Prime Factorization

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

2 x 139 x 175 x 649 x 178 = 5620145300

Therefore, the lowest common multiple of 278,350,649,356 is 5620145300.

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.

278 x 350 x 649 x 356 = 22480581200

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.

278 : 1, 2, 139, 278

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

649 : 1, 11, 59, 649

356 : 1, 2, 4, 89, 178, 356

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,350,649,356, is 1.

Now, the common factors can be found like this.

278:2x 139

350:2x 5x 5x 7

649:11x 59

356:2x 2x 89

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 = 22480581200/(1x4)

LCM = 22480581200/4

LCM = 5620145300

Thus, we can understand that the LCM of 278,350,649,356 is 5620145300.
