Given numbers are 661,573,398,370

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

The LCM of 661,573,398,370 is 27887583390.

Find LCM of 661,573,398,370 with Prime Factorization

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

2 x 661 x 573 x 199 x 185 = 27887583390

Therefore, the lowest common multiple of 661,573,398,370 is 27887583390.

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.

661 x 573 x 398 x 370 = 55775166780

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.

661 : 1, 661

573 : 1, 3, 191, 573

398 : 1, 2, 199, 398

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,573,398,370, is 1.

Now, the common factors can be found like this.

661:661

573:3x 191

398:2x 199

370:2x 5x 37

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 = 55775166780/(1x2)

LCM = 55775166780/2

LCM = 27887583390

Thus, we can understand that the LCM of 661,573,398,370 is 27887583390.
