Given numbers are 680,193,637,454

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

The LCM of 680,193,637,454 is 18977172760.

Find LCM of 680,193,637,454 with Prime Factorization

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

2 x 340 x 193 x 637 x 227 = 18977172760

Therefore, the lowest common multiple of 680,193,637,454 is 18977172760.

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.

680 x 193 x 637 x 454 = 37954345520

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

193 : 1, 193

637 : 1, 7, 13, 49, 91, 637

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,193,637,454, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

193:193

637:7x 7x 13

454:2x 227

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

2 = 2

Therefore, the value for common factors is 2.

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 = 37954345520/(1x2)

LCM = 37954345520/2

LCM = 18977172760

Thus, we can understand that the LCM of 680,193,637,454 is 18977172760.
