Given numbers are 246,642,661,780

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

The LCM of 246,642,661,780 is 2261849460.

Find LCM of 246,642,661,780 with Prime Factorization

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

2 x 3 x 41 x 107 x 661 x 130 = 2261849460

Therefore, the lowest common multiple of 246,642,661,780 is 2261849460.

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.

246 x 642 x 661 x 780 = 81426580560

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.

246 : 1, 2, 3, 6, 41, 82, 123, 246

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

661 : 1, 661

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 246,642,661,780, is 1.

Now, the common factors can be found like this.

246:2x 3x 41

642:2x 3x 107

661:661

780:2x 2x 3x 5x 13

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 81426580560/(1x36)

LCM = 81426580560/36

LCM = 2261849460

Thus, we can understand that the LCM of 246,642,661,780 is 2261849460.
