Given numbers are 704,970,390,434

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

The LCM of 704,970,390,434 is 2889606720.

Find LCM of 704,970,390,434 with Prime Factorization

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

2 x 5 x 352 x 97 x 39 x 217 = 2889606720

Therefore, the lowest common multiple of 704,970,390,434 is 2889606720.

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.

704 x 970 x 390 x 434 = 115584268800

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.

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

970 : 1, 2, 5, 10, 97, 194, 485, 970

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

434 : 1, 2, 7, 14, 31, 62, 217, 434

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,970,390,434, is 2.

Now, the common factors can be found like this.

704:2x 2x 2x 2x 2x 2x 11

970:2x 5x 97

390:2x 3x 5x 13

434:2x 7x 31

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 5 = 20

Therefore, the value for common factors is 20.

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 = 115584268800/(2x20)

LCM = 115584268800/40

LCM = 2889606720

Thus, we can understand that the LCM of 704,970,390,434 is 2889606720.
