LCM Formula to Find Lowest Common Multiple of 282,455,972,786,378

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.

282 x 455 x 972 x 786 x 378 = 37054513510560

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.

282 : 1, 2, 3, 6, 47, 94, 141, 282

455 : 1, 5, 7, 13, 35, 65, 91, 455

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

786 : 1, 2, 3, 6, 131, 262, 393, 786

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,455,972,786,378, is 1.

Now, the common factors can be found like this.

282:2x 3x 47

455:5x 7x 13

972:2x 2x 3x 3x 3x 3x 3

786:2x 3x 131

378:2x 3x 3x 3x 7

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 3x 3x 7 = 13608

Therefore, the value for common factors is 13608.

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 = 37054513510560/(1x13608)

LCM = 37054513510560/13608

LCM = 2722994820

Thus, we can understand that the LCM of 282,455,972,786,378 is 2722994820.
