Given numbers are 457,780,343,149,944

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

The LCM of 457,780,343,149,944 is 4299353887920.

Find LCM of 457,780,343,149,944 with Prime Factorization

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

2 x 2 x 457 x 195 x 343 x 149 x 236 = 4299353887920

Therefore, the lowest common multiple of 457,780,343,149,944 is 4299353887920.

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.

457 x 780 x 343 x 149 x 944 = 17197415551680

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.

457 : 1, 457

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

343 : 1, 7, 49, 343

149 : 1, 149

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,780,343,149,944, is 1.

Now, the common factors can be found like this.

457:457

780:2x 2x 3x 5x 13

343:7x 7x 7

149:149

944:2x 2x 2x 2x 59

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17197415551680/(1x4)

LCM = 17197415551680/4

LCM = 4299353887920

Thus, we can understand that the LCM of 457,780,343,149,944 is 4299353887920.
