Given numbers are 142,437,866,236,990

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

The LCM of 142,437,866,236,990 is 1569440602620.

Find LCM of 142,437,866,236,990 with Prime Factorization

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

2 x 71 x 437 x 433 x 118 x 495 = 1569440602620

Therefore, the lowest common multiple of 142,437,866,236,990 is 1569440602620.

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.

142 x 437 x 866 x 236 x 990 = 12555524820960

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.

142 : 1, 2, 71, 142

437 : 1, 19, 23, 437

866 : 1, 2, 433, 866

236 : 1, 2, 4, 59, 118, 236

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,437,866,236,990, is 1.

Now, the common factors can be found like this.

142:2x 71

437:19x 23

866:2x 433

236:2x 2x 59

990:2x 3x 3x 5x 11

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 2 = 8

Therefore, the value for common factors is 8.

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 = 12555524820960/(1x8)

LCM = 12555524820960/8

LCM = 1569440602620

Thus, we can understand that the LCM of 142,437,866,236,990 is 1569440602620.
