Given numbers are 354,940,193,640

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

The LCM of 354,940,193,640 is 1027562880.

Find LCM of 354,940,193,640 with Prime Factorization

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

2 x 2 x 5 x 177 x 47 x 193 x 32 = 1027562880

Therefore, the lowest common multiple of 354,940,193,640 is 1027562880.

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.

354 x 940 x 193 x 640 = 41102515200

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

193 : 1, 193

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,940,193,640, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

940:2x 2x 5x 47

193:193

640:2x 2x 2x 2x 2x 2x 2x 5

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 5 = 40

Therefore, the value for common factors is 40.

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 = 41102515200/(1x40)

LCM = 41102515200/40

LCM = 1027562880

Thus, we can understand that the LCM of 354,940,193,640 is 1027562880.
