Given numbers are 642,370,743,194,947

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

The LCM of 642,370,743,194,947 is 8106199418490.

Find LCM of 642,370,743,194,947 with Prime Factorization

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

2 x 321 x 185 x 743 x 97 x 947 = 8106199418490

Therefore, the lowest common multiple of 642,370,743,194,947 is 8106199418490.

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 370 x 743 x 194 x 947 = 32424797673960

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

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

743 : 1, 743

194 : 1, 2, 97, 194

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,370,743,194,947, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

370:2x 5x 37

743:743

194:2x 97

947:947

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 = 32424797673960/(1x4)

LCM = 32424797673960/4

LCM = 8106199418490

Thus, we can understand that the LCM of 642,370,743,194,947 is 8106199418490.
