Given numbers are 164,487,220,742

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

The LCM of 164,487,220,742 is 1629706540.

Find LCM of 164,487,220,742 with Prime Factorization

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

2 x 2 x 41 x 487 x 55 x 371 = 1629706540

Therefore, the lowest common multiple of 164,487,220,742 is 1629706540.

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.

164 x 487 x 220 x 742 = 13037652320

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.

164 : 1, 2, 4, 41, 82, 164

487 : 1, 487

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 164,487,220,742, is 1.

Now, the common factors can be found like this.

164:2x 2x 41

487:487

220:2x 2x 5x 11

742:2x 7x 53

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 2 = 8

Therefore, the value for common factors is 8.

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 = 13037652320/(1x8)

LCM = 13037652320/8

LCM = 1629706540

Thus, we can understand that the LCM of 164,487,220,742 is 1629706540.
