Given numbers are 760,455,876,520,820

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

The LCM of 760,455,876,520,820 is 620987640.

Find LCM of 760,455,876,520,820 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 19 x 7 x 219 x 1 x 41 = 620987640

Therefore, the lowest common multiple of 760,455,876,520,820 is 620987640.

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.

760 x 455 x 876 x 520 x 820 = 129165429120000

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.

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

455 : 1, 5, 7, 13, 35, 65, 91, 455

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,455,876,520,820, is 1.

Now, the common factors can be found like this.

760:2x 2x 2x 5x 19

455:5x 7x 13

876:2x 2x 3x 73

520:2x 2x 2x 5x 13

820:2x 2x 5x 41

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 2x 2x 2x 2x 5x 5x 5x 13 = 208000

Therefore, the value for common factors is 208000.

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 = 129165429120000/(1x208000)

LCM = 129165429120000/208000

LCM = 620987640

Thus, we can understand that the LCM of 760,455,876,520,820 is 620987640.
