Given numbers are 691,942,845,472,684

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

The LCM of 691,942,845,472,684 is 7398991318680.

Find LCM of 691,942,845,472,684 with Prime Factorization

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

2 x 2 x 3 x 691 x 157 x 845 x 118 x 57 = 7398991318680

Therefore, the lowest common multiple of 691,942,845,472,684 is 7398991318680.

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.

691 x 942 x 845 x 472 x 684 = 177575791648320

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.

691 : 1, 691

942 : 1, 2, 3, 6, 157, 314, 471, 942

845 : 1, 5, 13, 65, 169, 845

472 : 1, 2, 4, 8, 59, 118, 236, 472

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,942,845,472,684, is 1.

Now, the common factors can be found like this.

691:691

942:2x 3x 157

845:5x 13x 13

472:2x 2x 2x 59

684:2x 2x 3x 3x 19

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 3 = 24

Therefore, the value for common factors is 24.

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 = 177575791648320/(1x24)

LCM = 177575791648320/24

LCM = 7398991318680

Thus, we can understand that the LCM of 691,942,845,472,684 is 7398991318680.
