Given numbers are 780,146,116,561,473

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

The LCM of 780,146,116,561,473 is 13277781660.

Find LCM of 780,146,116,561,473 with Prime Factorization

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

2 x 2 x 3 x 11 x 65 x 73 x 29 x 17 x 43 = 13277781660

Therefore, the lowest common multiple of 780,146,116,561,473 is 13277781660.

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.

780 x 146 x 116 x 561 x 473 = 3505334358240

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.

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

146 : 1, 2, 73, 146

116 : 1, 2, 4, 29, 58, 116

561 : 1, 3, 11, 17, 33, 51, 187, 561

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,146,116,561,473, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

146:2x 73

116:2x 2x 29

561:3x 11x 17

473:11x 43

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 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 3505334358240/(1x264)

LCM = 3505334358240/264

LCM = 13277781660

Thus, we can understand that the LCM of 780,146,116,561,473 is 13277781660.
