Given numbers are 414,985,128,940

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

The LCM of 414,985,128,940 is 1226632320.

Find LCM of 414,985,128,940 with Prime Factorization

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

2 x 2 x 5 x 207 x 197 x 32 x 47 = 1226632320

Therefore, the lowest common multiple of 414,985,128,940 is 1226632320.

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.

414 x 985 x 128 x 940 = 49065292800

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.

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

985 : 1, 5, 197, 985

128 : 1, 2, 4, 8, 16, 32, 64, 128

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,985,128,940, is 1.

Now, the common factors can be found like this.

414:2x 3x 3x 23

985:5x 197

128:2x 2x 2x 2x 2x 2x 2

940:2x 2x 5x 47

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 5 = 40

Therefore, the value for common factors is 40.

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 = 49065292800/(1x40)

LCM = 49065292800/40

LCM = 1226632320

Thus, we can understand that the LCM of 414,985,128,940 is 1226632320.
