11 67, 31, 11, 11, 19
67, 31, 1, 1, 19

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

2 x 3 x 3 x 5 x 7 x 11 x 67 x 31 x 1 x 1 x 19 = 273478590

Therefore, the lowest common multiple of 938,434,693,990,570 is 273478590.

LCM Formula to Find Lowest Common Multiple of 938,434,693,990,570

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.

938 x 434 x 693 x 990 x 570 = 159197356810800

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

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

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

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

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,434,693,990,570, is 1.

Now, the common factors can be found like this.

938:2x 7x 67

434:2x 7x 31

693:3x 3x 7x 11

990:2x 3x 3x 5x 11

570:2x 3x 5x 19

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 3x 3x 5x 7x 7x 11 = 582120

Therefore, the value for common factors is 582120.

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 = 159197356810800/(1x582120)

LCM = 159197356810800/582120

LCM = 273478590

Thus, we can understand that the LCM of 938,434,693,990,570 is 273478590.
