Given numbers are 771,702,141,406

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

The LCM of 771,702,141,406 is 1721329974.

Find LCM of 771,702,141,406 with Prime Factorization

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

2 x 3 x 257 x 117 x 47 x 203 = 1721329974

Therefore, the lowest common multiple of 771,702,141,406 is 1721329974.

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.

771 x 702 x 141 x 406 = 30983939532

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.

771 : 1, 3, 257, 771

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

141 : 1, 3, 47, 141

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,702,141,406, is 1.

Now, the common factors can be found like this.

771:3x 257

702:2x 3x 3x 3x 13

141:3x 47

406:2x 7x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 30983939532/(1x18)

LCM = 30983939532/18

LCM = 1721329974

Thus, we can understand that the LCM of 771,702,141,406 is 1721329974.
