Given numbers are 354,121,398,803

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

The LCM of 354,121,398,803 is 622249518.

Find LCM of 354,121,398,803 with Prime Factorization

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

2 x 11 x 177 x 11 x 199 x 73 = 622249518

Therefore, the lowest common multiple of 354,121,398,803 is 622249518.

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 121 x 398 x 803 = 13689489396

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

121 : 1, 11, 121

398 : 1, 2, 199, 398

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,121,398,803, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

121:11x 11

398:2x 199

803:11x 73

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 13689489396/(1x22)

LCM = 13689489396/22

LCM = 622249518

Thus, we can understand that the LCM of 354,121,398,803 is 622249518.
