Given numbers are 642,946,523,140

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

The LCM of 642,946,523,140 is 11117212260.

Find LCM of 642,946,523,140 with Prime Factorization

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

2 x 321 x 473 x 523 x 70 = 11117212260

Therefore, the lowest common multiple of 642,946,523,140 is 11117212260.

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.

642 x 946 x 523 x 140 = 44468849040

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

946 : 1, 2, 11, 22, 43, 86, 473, 946

523 : 1, 523

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,946,523,140, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

946:2x 11x 43

523:523

140:2x 2x 5x 7

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 = 44468849040/(1x4)

LCM = 44468849040/4

LCM = 11117212260

Thus, we can understand that the LCM of 642,946,523,140 is 11117212260.
