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

2 x 2 x 3 x 5 x 11 x 89 x 47 x 29 x 3 = 240187860

Therefore, the lowest common multiple of 979,564,580,990 is 240187860.

LCM Formula to Find Lowest Common Multiple of 979,564,580,990

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.

979 x 564 x 580 x 990 = 317047975200

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.

979 : 1, 11, 89, 979

564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,564,580,990, is 1.

Now, the common factors can be found like this.

979:11x 89

564:2x 2x 3x 47

580:2x 2x 5x 29

990:2x 3x 3x 5x 11

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 3x 5x 11 = 1320

Therefore, the value for common factors is 1320.

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 = 317047975200/(1x1320)

LCM = 317047975200/1320

LCM = 240187860

Thus, we can understand that the LCM of 979,564,580,990 is 240187860.
