Given numbers are 684,641,986,406

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

The LCM of 684,641,986,406 is 1513070244.

Find LCM of 684,641,986,406 with Prime Factorization

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

2 x 29 x 342 x 641 x 17 x 7 = 1513070244

Therefore, the lowest common multiple of 684,641,986,406 is 1513070244.

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.

684 x 641 x 986 x 406 = 175516148304

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

641 : 1, 641

986 : 1, 2, 17, 29, 34, 58, 493, 986

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 684,641,986,406, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

641:641

986:2x 17x 29

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 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 175516148304/(1x116)

LCM = 175516148304/116

LCM = 1513070244

Thus, we can understand that the LCM of 684,641,986,406 is 1513070244.
