Given numbers are 237,781,642,840

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

The LCM of 237,781,642,840 is 5545506120.

Find LCM of 237,781,642,840 with Prime Factorization

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

2 x 3 x 79 x 781 x 107 x 140 = 5545506120

Therefore, the lowest common multiple of 237,781,642,840 is 5545506120.

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.

237 x 781 x 642 x 840 = 99819110160

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.

237 : 1, 3, 79, 237

781 : 1, 11, 71, 781

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 237,781,642,840, is 1.

Now, the common factors can be found like this.

237:3x 79

781:11x 71

642:2x 3x 107

840:2x 2x 2x 3x 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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 99819110160/(1x18)

LCM = 99819110160/18

LCM = 5545506120

Thus, we can understand that the LCM of 237,781,642,840 is 5545506120.
