Given numbers are 244,980,638,920,974

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

The LCM of 244,980,638,920,974 is 427202107640.

Find LCM of 244,980,638,920,974 with Prime Factorization

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

2 x 2 x 5 x 61 x 49 x 319 x 46 x 487 = 427202107640

Therefore, the lowest common multiple of 244,980,638,920,974 is 427202107640.

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.

244 x 980 x 638 x 920 x 974 = 136704674444800

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.

244 : 1, 2, 4, 61, 122, 244

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

638 : 1, 2, 11, 22, 29, 58, 319, 638

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 244,980,638,920,974, is 2.

Now, the common factors can be found like this.

244:2x 2x 61

980:2x 2x 5x 7x 7

638:2x 11x 29

920:2x 2x 2x 5x 23

974:2x 487

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 2x 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 136704674444800/(2x160)

LCM = 136704674444800/320

LCM = 427202107640

Thus, we can understand that the LCM of 244,980,638,920,974 is 427202107640.
