Given numbers are 406,695,940,902,690

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

The LCM of 406,695,940,902,690 is 825399733620.

Find LCM of 406,695,940,902,690 with Prime Factorization

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

2 x 5 x 203 x 139 x 94 x 451 x 69 = 825399733620

Therefore, the lowest common multiple of 406,695,940,902,690 is 825399733620.

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.

406 x 695 x 940 x 902 x 690 = 165079946724000

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

695 : 1, 5, 139, 695

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

902 : 1, 2, 11, 22, 41, 82, 451, 902

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,695,940,902,690, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

695:5x 139

940:2x 2x 5x 47

902:2x 11x 41

690:2x 3x 5x 23

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 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 165079946724000/(1x200)

LCM = 165079946724000/200

LCM = 825399733620

Thus, we can understand that the LCM of 406,695,940,902,690 is 825399733620.
