Given numbers are 140,427,273,778

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

The LCM of 140,427,273,778 is 129560340.

Find LCM of 140,427,273,778 with Prime Factorization

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

2 x 7 x 10 x 61 x 39 x 389 = 129560340

Therefore, the lowest common multiple of 140,427,273,778 is 129560340.

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.

140 x 427 x 273 x 778 = 12696913320

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

427 : 1, 7, 61, 427

273 : 1, 3, 7, 13, 21, 39, 91, 273

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,427,273,778, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

427:7x 61

273:3x 7x 13

778:2x 389

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 12696913320/(1x98)

LCM = 12696913320/98

LCM = 129560340

Thus, we can understand that the LCM of 140,427,273,778 is 129560340.
