Given numbers are 162,546,107,780

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

The LCM of 162,546,107,780 is 15773940.

Find LCM of 162,546,107,780 with Prime Factorization

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

2 x 3 x 13 x 27 x 7 x 107 x 10 = 15773940

Therefore, the lowest common multiple of 162,546,107,780 is 15773940.

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.

162 x 546 x 107 x 780 = 7382203920

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.

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

107 : 1, 107

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 162,546,107,780, is 1.

Now, the common factors can be found like this.

162:2x 3x 3x 3x 3

546:2x 3x 7x 13

107:107

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 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 7382203920/(1x468)

LCM = 7382203920/468

LCM = 15773940

Thus, we can understand that the LCM of 162,546,107,780 is 15773940.
